Question:
When an ideal gas is compressed adiabatically, its temperature rises the molecules on the average have more kinetic energy than before. The kinetic energy increases
When an ideal gas is compressed adiabatically, its temperature rises the molecules on the average have more kinetic energy than before. The kinetic energy increases

- because of collisions with moving parts of the wall only
- because of collisions with the entire wall
- because the molecules gets accelerated in their motion inside the volume
- because the redistribution of energy amongst the molecules

The Correct Option is A
Solution and Explanation
If an ideal gas is compressed adiabatically, its temperature rises, because heat produced cannot be lost to the surroundings. Each molecule has more $KE$ than before because of collisions of molecules with moving parts of the wall (i.e. piston compressing the gas).
