Answer to Question #41979 in Other Chemistry for mary
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
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.
