A frictionless piston cylinder device contains a saturated liquid (refrigerant-134a). The refrigerant is heated until it reaches to some temperature. Determine the work done and heat transferred to the refrigerant during this process.
I just want to make sure that I understand this topic. I will have to use tables for this.(a)The saturated liquid is turned into super heated gas.
(b) Heat transferred is the change in the internal energy u.
(c)Work done is the change in ΔP*V where P is pressure and V is volume
h=u+PV
Are those 3 assumptions correct?
Thanks
