How Do You Prove Air Has Volume

Air, and how it behaves and moves, is  important to understanding the basic processes that lead to weather. But because air (and the atmosphere) is invisible, it can be hard to think of it as having properties like mass, volume, and pressure—or even being there at all! These simple activities and demos will help you prove that air indeed has volume (takes up space). Air Volume Demonstrations Difficulty: Easy Time Required: Under 5 minutes Activity 1: Underwater Air Bubbles Materials: A small (5-gallon) fish tank or other large containerA juice or shot glassTap water Procedure: Fill the tank or large container about 2/3 full of water. Invert the drinking glass and push it straight down into the water.Ask, What do you see inside the glass? (Answer: water, and air trapped at the top)Now, slightly tip the glass to allow a bubble of air to escape and float to the surface of the water.Ask, Why does this happen? (Answer: The air bubbles prove there is air that has volume within the glass. The air, as it moves out of the glass, is replaced by the water proving air takes up space.) Activity 2: Air Balloons Materials: a deflated balloona 1-liter soda bottle (with label removed) Procedure: Lower the deflated balloon into the neck of the bottle. Stretch the open end of the balloon over the mouth of the bottle.Ask, What do you think will happen to the balloon if you tried to inflate it like this (inside the bottle)? Will the balloon inflate until it presses against the sides of the bottle? Will it pop?Next, put your mouth on the bottle and try to blow up the balloon.Discuss why the balloon does nothing. (Answer: To start with, the bottle was full of air. Since air takes up space, youre unable to blow up the balloon because the air trapped inside the bottle keeps it from inflating.) Alternate Example Another very simple way to demonstrate that air takes up space? Take a balloon or brown paper lunch bag. Ask: Whats inside of it? Then blow into the bag and hold your hand tight around the top of it. Ask: Whats in the bag now? (Answer: air) Conclusions Air is made up of a variety of gases. And although you cant see it, the above activities have helped us prove that it has weight, albeit not much weight—air just isnt very dense! Anything with a weight also has mass, and by the laws of physics, when something has mass it also takes up space.     Source Teach Engineering: Curriculum for K-12 Teachers.

Essay about The Medicine Man - 528 Words

The Medicine Man The film â€Å"Medicine Man† gives a very clear indication of the consequences of habitat destruction. In the film, a professor and his research assistant set out to find a plant that holds the cure of cancer, only to have it destroyed by land clearing in the Amazon Basin. The land clearing also severely disrupts the peaceful, sustainable lifestyle of a tribe of natives and a huge amount of flora and fauna. It shows us the damage we wrought with our deforestation on a slightly exaggerated, nut no less effective scale. The main idea of the film is to show habitat destruction and its impacts on the environment. It succeeds in showing the rapid rate at which logging and land–clearing is taking place. Such human activities†¦show more content†¦Wealthy corporations usually commission such land–clearings and use the land for farming. However they do not think about the native plants, animals and people who have more right to the land than they do. The film also highlights the difference between the city modern, city lifestyle and the lifestyle of the native people. The people of the city live more luxuriously than the native people, but their lifestyle is not sustainable. The â€Å"city people† suck their environment dry in order to gain their creature comforts, while the native people make a minimal impact on their environment, only taking what they need. The environment can cope with the impacts made by the indigenous people but not the city dwellers. As a result, the environment in which we live is heavily polluted whereas that of the indigenous people is not. The film also makes a subtle point about biodiversity. In a rainforest such as the Amazon, countless different species can be found in a relatively small area. Some of these species are found only in that area. Therefore by clearing the forest without investigating the flora and fauna first could result in extinction of a species. For example, in the film the plant and the species of ant that holds the key to the cure of cancer had never been found anywhere else in the world. So the destruction of that part of the rainforest could well have meant genocide of the two species. If it was real life instead of aShow MoreRelatedIs Medicine Altered ( Wo ) Man?

Some of these being that the Roman Empire showed identical mentality on everything sport, athletic, spectator, and more that have been translated to modern day sports and athletics.

Demand Risk in Transport Infrastructure Projects Essay Sample free essay sample

The Demand hazard of a PPP Rail Transport Infrastructure Project refers to the hazard with respects to the figure of riders that is required in order to guarantee equal gross coevals to cover the project’s operational and care costs. Merna and Owen ( Merna A ; Owen. 1998 ) noted that â€Å"demand hazard is the greatest hazard to the concessioner under the payment mechanism† . The demand hazard is cardinal for a market-led service where gross coevals is critical to the ultimate success of the undertaking. Brocklebank. Burnett. Ras A ; Walt ( Brocklebank. Burnett. Ras A ; Walt. 2001 ) describes the demand forecasts or gross coevals as â€Å"vital to the development of a concern case† . Mackie. Nellthrop and Laird ( Mackie. Nellthrop and Laird. 2005 ) note that â€Å"demand prognosiss are cardinal to an economic appraisal† for rail conveyance substructure undertakings. The Concept of Demand RiskBurger ( Burger. P. 2006 ) noted that when a demand for a service exist. with outwardness features ( demand side hazard ) . the type of contract through which the substructure is constructed. managed and operated. depends on the ability of the authorities to reassign the demand hazard to the concessioner every bit good as the degree of the competition in the unfastened market. Grimsley and Lewis ( Grimsley and Lewis. 2005 ) note that hazard transportation and the degree of competition during the stamp procedure. is critical to guarantee the concessioner focuses on being â€Å"technically and X-efficient† . X-efficiency refers to the ability of the concessioner to run the service without uneconomical inputs ( Burger. P. 2006 ) . Fourie and Burger ( 2000 ) conclude that the chief drivers of efficiency and value for money in elastic demand based PPP Infrastructure undertakings is demand hazard transportation. The demand hazard associated with substructure undertakings are inherently higher than undertakings that deliver a merchandise as the substructure undertakings are fixed assets that can’t easy move or follow the mark market. The ability of a concessioner to pull off the demand hazard for a rail conveyance substructure undertaking is highly limited and the demand hazard is hence historically transferred to the grantor of the undertaking who is deemed to be in a better place to pull off and extenuate the hazard. Demand Risk in Rail Transport Infrastructure undertakingsDemand hazard prediction is paramount to the success of a rail conveyance substructure undertaking. Demand prediction allows the grantor to place the figure of possible riders. supply an estimation of possible gross coevals. set up feasibleness and place the demands of the mark market. Rail Transport undertakings are market-led undertakings and are normally extremely reliant on the gross coevals. The ability of establishments to accurately calculate demand for a conveyance undertaking over a long grant contract period remains extremely controversial. The high figure influences on the demand for a service is highly hard to foretell. Historic research of Public Private Partnerships ( PPP’s ) Transport substructure undertakings would propose that the demand prediction is grossly inaccurate. As a consequence the economic feasibleness of rail conveyance substructure undertakings are questionable. Furthermore the demand prediction requires a big sum of premises to be made. all of which can be easy manipulated to turn out feasibleness. The ultimate intent of the demand prediction is to turn out profitableness and feasibleness in order to pull funders. investors and competitory stamps. Below is a list of factors associated with or that have an impact on demand hazard for rail conveyance substructure undertakings: ?Recession?Economic down bend?Quality of the service?Social acceptableness?Consumer opposition to pay and utilize the system?Safety?Changes to demographic nodes environing the Stationss?Associated feeder or distribution systems to present the demand to the service?The ability to run into an addition in the demand?Competition of alternate methods of conveyance Demand Risk Mitigation in Rail Transport Infrastructure undertakings Merna and Owen ( Merna A ; Owen. 1998 ) noted that the success of a PPP undertaking depends non merely on the ability of the spouses to reassign hazard but to reassign to the hazard to the party most suited to extenuate the hazard. Merna and Al-Thani ( Merna A ; Al-Thani. 2010 ) concluded that in order to pull off demand hazard efficaciously it is critical to guarantee that the PPP contract promotes continues service bringing and productiveness. Historically the preferable method of demand hazard extenuation in a PPP Transport Infrastructure undertaking is the debut of a backing warrant. where the grantor guarantees the minimal backing or gross required to guarantee care and operational costs during the grant period is covered. However. the debut of a backing warrant reduces or eliminates the inducements for a concessioner to increase service quality and increase demand or rider Numberss. The ability of a rail conveyance substructure concessioner to pull off the demand hazard is ab out impossible hence demand hazard is largely transferred to the grantor. Drumhead Demand hazard designation. transportation and extenuation are cardinal to the feasibleness and success of a PPP conveyance substructure undertaking. The ability to accurately calculate the demand for a service and the gross generated through the life rhythm of the service is critical to the economic feasibleness of a market-led substructure service. The debut of a backing warrant offered by the grantor transfers the demand hazard efficaciously to the public spouse. albeit that it provides small inducement to the private party or concessioner to better service bringing and increase demand for the service. Historic literature would propose that the demand hazard is of extreme importance in a gross or market-led substructure system. Mentions Brocklebank. P. . Burnett. S. L. . Ras. N. A ; VD Walt. G.
