Answer to Question #41979 in Chemistry for mary

Question

why is it that when a gas and liquid (of the same substance and amount) are compressed , the change in volume is much smaller in the liquide than in the gas

Answer 1

The volume of a gas particles is very small compared to the overall gas volume, while in liquid the distance between particles is comparable with particles size. In other words the space between gas particles is much larger than the spaces between liquid particles. So, the change in volume under compression is much larger in gas than that in liquid.
