1. (Sec 19-6 & 19-7) Look at Figure 19-32 at the end of chapter 19. In the process of taking a gas from state a to state 0, along the curved path, 80 J of heat leave the system and 55 J ofwork are done on the system. We write Qabc = -80 J and Watn: = -55 J. A. Determine the change in internal energy, U3 - Uc- B. When the gas is taken along the path gda, the work done on the gas W = 38 J. How much heat Q is added to the gas in the process 941a? C. If Pa = 2.5Pd, how much work is done by the gas in the process abc? D. What is Q for path abc? E. If Ua - U1, = 10 J, what is Q for the process be? P b a C d V
