Asked by Baker

You kick a soccer ball, compressing it suddenly to 2/3 of its original volume. In the process, you do 410 J of work on the air (assumed to be an ideal gas) inside the ball.
(a) What is the change in internal energy of the air inside the ball due to being com-pressed?
(b) Does the temperature of the air inside the ball rise or fall due to being compressed? Explain.

Q=0
delta U= -W
delta U= 410j
but since it is compression
delta U= -410j

Temp should rise since the pressure of the system increased
