question_answer 27)

                  When an ideal gas is compressed adiabatically, its temperature rises: the molecules on the average have more kinetic energy than before. The kinetic energy increase.                 (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 of redistribution of energy amongst the molecules.

Answer:

..                 (a) \[K.E.=\frac{{{p}^{2}}}{2m}\]
