Question

In the process of taking a gas from state a to state c along the curved path shown in the figure (Figure 1) , 85J of heat leaves the system and 60J of work is done on the system. A. Determine the change in internal energy, Ua-Uc B.When the gas is taken along the path cda, the work done by the gas is W = 31J. How much heat Q is added to the gas in the process cda? C.If Pa = 2.4,Pd, how much work is done by the gas in the process abc? D.What is Q for path abc? E. If Ua - Ub = 15J , what is Q for the process bc?

Explanation / Answer

please provide the pic and help us to help you! Q = U + W -85 = Ua-Uc + 60 Ua-Uc = - 145J
