For a certain sample of gas particles, the average kinetic energy depends on density. True or False?

thnx!For a certain sample of gas particles, the average kinetic energy depends on density. True or False?
False


Kinetic energy - is energy possessed by a molecule by virtue of its movement or motion. Higher its velocity, higher is its kinetic energy.


KE = 0.5 * m * v^2





- It depends on temperature and


- how heavy the molecule is (its molecular mass). - heavier the particle, slowly will it move.For a certain sample of gas particles, the average kinetic energy depends on density. True or False?
I beleive true... since gas is compressable and compressing is a way of storing energy.
true nearly all the time.
