N an empty rubber raft the pressure is approximately constant. You push on a large air pump that pushes 1.0 L(1.0× 10-3m3) of air into the raft. You exert a 15 N force while pushing the pump handle 6.0×10-2 m .
Determine the work done on the gas.
If all of the work is converted to thermal energy of the 1.0 L of gas, what is the temperature increase of the gas? Assume that the air obeys the ideal gas law and is initially at 293 K.
