A compressor for a jackhammer expands the air in the hammer’s cylinder at a constant pressure of 8.6 x 10^5 Pa. The increase in the cylinder’s volume is 4.0^5 x 10^-4 m^3. During the process, 9.5 J of energy is transferred out of the cylinder as heat.
A. What is the work done by the air
B. What is the change in the air’s internal energy
C. What type of ideal thermodynamic process does this approximate
