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

Options

A. because of collision with moving parts of the wall only.
B. because of collisionws with the entire wall.
C. because the molecules gets accelerated in their motion inside the volume.
D. because the redistribution of energy amongst the molecules.

Answer

A

Explanation

If an ideal gas is compressed adiabatically, its trmperature rises, because heat produced cannot be lost to the surrounding. Each molecule has more KE than before because of collisios of molecules with moving parts of the wall (i.e., piston comperssing the gas).
