How Does Temperature Change Affect Pressure in a Piston-Cylinder System?

pleasehelpme6 · Sep 18, 2010

Warm air is contained in a piston-cylinder assembly cools slowly from volume of 0.003 m^3 to 0.002 m^3. During the process a spring exerts a force that varies linearly from an initial value of 900 N to final value of 0. Patm = 100 kPa and the area of the piston face is 0.018 m^2.

Or,

V1 = 0.003 m^3
V2 = 0.002 m^3

F1 = 900 N
F2 = 0

Patm = 100 kPa

Piston-cylinder diagram labeled Fig. P1.42 with air in the cylinder, piston area A = 0.018 m^2, Patm = 100 kPa, and a spring force that varies linearly from 900 N to zero as V1 = 0.003 m^3 to V2 = 0.00 (cut off).

I'm not exactly sure where to start here. Can someone help me figure out what formula to use?

PV = nRT applies to the air in the piston.
F = kx applies to the spring.
What is the question?
