Ideal Gases:An ideal gas is defined as a gas which has molecules with no interactions between each other. In an ideal gas, the molecules are assumed to have no volumes as well.Answer and Explanation: Actual gases deviate from the ideal behavior because the gas molecules do have volumes and...
Why do substances expand when the temperature is increased? Why are gases easier to compress than liquids and solids? How come heat engines are more efficient when run at high temperatures? Why does a bottle of tire pump feel hot when you pump air in the tire, but when a...

In ethanol or ammonia plants, for example, emissions are essentially a pure CO2 stream, making it both easier and cheaper to condition and compress. In contrast, cement or power plants emit flue gas with 10–20% CO2. Before disposing of it, the CO2 must be separated from other gase...
It looks like the ripples in a pond after a stone has been tossed in.That’s because one of the small galaxies on the right pass through it.And that bright ring around it, that’s where colliding and compressing gases forming stars. ...
Acoelomateslack a fluid-filled body cavity between the body wall and digestive tract. This can cause some serious disadvantages. Fluid compression is negligible, while the tissue surrounding the organs of these animals will compress. ... The coelom can be used for diffusion of gases and metabolit...
The process of fracking is to drill into the earth and pump water and other chemicals into the earth to create cracks or fissure in the shale rock, allowing the gases to be released into a well for collection. The chemicals used in fracking can include water, sand, salt, citric acid, ...
