When an ideal gas is compressed adiabaticall, is temperature rises the molecule on the average have nore kinetic energy than before. The kinetic energy increases,

Options

A. Because of collision with moving parts of the walls only
B. Because of collision with the entire wall
C. Because of molecules gats accelerated in this motion inside the volume
D. Because of redistribution of energy amongst the molecules

Answer

A

Explanation

Sol, (a) Since the gas is ideal and the collisions of the molecules are elastic. When the molecules collides with the moving parts of the wall. Its kinetic energy increases. But the total kinetic energy of the system will remain conserved. When the gas is compressed adialbatically, the totla work done on the gas increases, its internal energy which in turn increases the KE of gas molecules and hence, the collisions between molecules also increases.
