Question:

Consider a small air pistol (Fig. P6.86) with a cylinder volume of 1 cm³ at 250 kPa, 27◦C. The bullet acts as a piston initially held by a trigger. The bullet is released, so the air expands in an adiabatic process. If the pressure should be 120 kPa as the bullet leaves the cylinder, find the final volume and the work done by the air.
