1. In the process of taking a gas from state a to state c, along the curved path, 80 J of heat leave the system and 55 J of work are done on the system. We write Qa→e=-80 J and Wa +=-55 J. A. Determine the change in internal energy, U, - Uc. B. When the gas is taken along the path cda, the work done on the gas W= 38 J. How much heat Q is added to the gas in the process cda? C. If P. = 2.5På, how much work is done by the gas in the process abc? D. What is Q for path abc? E. If U. - Us = 10 J, what is Q for the process bc?
