Homework Help: Chemistry (Internal Energy)

Posted by Simon on Tuesday, October 2, 2012 at 11:26pm.

5 kg of steam contained within a piston-cylinder assembly undergoes an expansion from state 1, where the specific internal energy U(1) is = 2710 [kJ/kg] to state 2, where U(2) = 2660 [kJ/kg].

During the process, there is heat transfer to the steam with a magnitude of 80 [kJ]. Also, a paddle wheel transfers energy to the steam by work in the amount of 18.5 [kJ]. Determine the energy transfer by work from the steam to the piston during the process
