Question

When an ideal gas is compressed adiabatically , its temperature rises the molecules on the average have more energy than before. The kinetic energy increases,
A. because of collisions with moving parts of the wall only
B. because of collisions with the entire wall
C. because the molecules gets accelerated in their motion inside the volume
D. because the redistribution of energy amongest the molecules

Answer 1

When the gas is compressed adiabatically, the total work done on the gas increases its internal energy which in turn increase the KE of gas molecules and hence, the collisions between molecules also increases.
