(a) The temperature of the air in the high pressure air tank when the air engine starts and the absolute pressure in the tank drops to 270 bar. Volume remains constant. (b) The mass of air in the pressurised air tank using the temperature and pressure from part 1 (a). Homework Equati...
Mass of air in the room m= volume of roomxxdensity of air =(5mxx4mxx3m)(1.20(kg)/(m^3))=72kg Weight of air, W=mg=(72kg)(9.8(m)/(s^2))=706N.
Born from the accessibility of mass air travel, modern international tourism has been popularized as “holiday-making” in regions that offer comparative advantages of sand, sun and sea. Travel is often portrayed (描绘成) as a tool for personal growth and tourism as an economic motor for destin...

The same molecules are in the air but occupy less space (volume) than when the molecules are free. Forcing these gas molecules together has some incredible consequences:As the number of molecules increases in a given volume, the mass of air also increases. As that mass of air increases, ...

Vapour density is the ratio of the mass of a given volume of vapour relative to the mass of the same given volume of air. Air has an arbitrary vapour density of 1, which makes it very straightforward to see if a particular vapour is heavier or lighter than air. ...
