change in linear momentum is zero because in ideal gas molecules energy of the molecules remains same after collision hence its initial velocity equals to final velocity..hence the change in momentum is zero..

Change in the linear momentum is zero because in ideal gas collisions , the energy of a molecule remains same.. so its initial velocity is equal to final velocity and mass is also same.

Momentum = mass x velocity

when neither mass nor velocity changes,, so Kinetic energy and momentum remains unchanged

A molecule of mass m of an ideal gas collides with the wall of a vessel with a velocity v and returns back with the same velocity. the change in linear momentum of a molecule is.
