H.W1: Warm air is contained in a piston-cylinder assembly oriented horizontally as shown in Figure below. The air cools slowly from an initial volume of 0.003 m’ to a final volume of 0.002 m². During the process, the spring exerts a force that varies linearly from an initial value of 900 N to a final value of zero. The atmospheric pressure is 100 kPa, and the area of the piston face is 0.018 m². Friction between the piston and the cylinder wall can be neglected. For the air, determine the initial and final pressures, in kPa, and the work, in kJ.

![H.W1: Warm air is contained in a piston-cylinder assembly oriented
horizontally as shown in Figure below. The air cools slowly from an
initial volume of 0.003 m to a final volume of 0.002 m'. During the
process, the spring exerts a force that varies linearly from an initial value
of 900 N to a final value of zero. The atmospheric pressure is 100 kPa,
and the area of the piston face is 0.018 m. Friction between the piston
and the cylinder wall can be neglected. For the air, determine the initial
and final pressures, in kPa, and the work, in kJ.
A = 0.018 m2
Patm = 100 kPa
