Question

When a basketball bounces against the ground and gets deformed and then recovers its shape, the air inside that ball is temporarily compressed. The compression ends when the ball recovers during the rebound. The temperature of air inside the ball

• A. Remains constant throughout the bounce, because thermal energy is conserved.
• B. Decreases during the deformation process and increases during the recovery processes.
• C. Increases during the deformation process and decreases during the recovery process.
• D. Increases during both the deformation and recovery processes.

Answer 1

The correct option is C Increases during the deformation process and decreases during the recovery process.

Its adiabatic process ,use $T{V}^{\gamma -1}$ = const
