A fluid is contained in a cylinder by a spring-loaded, frictionless piston so that the pressure in the fluid is linear function of the volume (p = a + bV). The internal energy of the fluid is given by the following equation U = 34 + 3.15 pV where U is in kJ, p in kPa and V in cubic metre. If the fluid changes from an initial state of 173 kPa, 0.03 m3 to a final state of 400 kPa, 0.06 m3 , with no work other than that done on the piston, find the direction and magnitude of the work and heat transfer.

Question

A fluid is contained in a cylinder by a spring-loaded, frictionless piston so that the pressure in the fluid is linear function of the volume (p = a + bV).
The internal energy of the fluid is given by the following equation U = 34 + 3.15 pV
where U is in kJ, p in kPa and V in cubic metre. If the fluid changes from an initial state of 173 kPa, 0.03 m3
to a final state of 400 kPa, 0.06 m3
, with
no work other than that done on the piston, find the direction and magnitude of the work and heat transfer.
