Hi,

I was working on my hwk, but would like to double check my answer. Could you please solve it?

H34 A frictionless vertical piston-cylinder device (see Fig. H34) contains 5 kg of H20, initially at p1 = 10 bar and T1 = 240C The device is cooled which causes the piston to descend, slowly with no acceleration, until it hits the stops at which point the volume of the water is 0.5 m3. Cooling continues until the temperature is T2 : 110C (nal state is state 2). Assume a quasiequillibrium process with negligible kinetic and potential energy effects. a. work [kJ] during process (indicate magnitude and direction) b. heat transfer [kJ] during process (indicate magnitude and direction) Figure H34
