Let assume the Diesel cycle, which is the one of most common thermodynamic cycles that can be found in automobile engines.One of key parameters of such engines is the change in volumes between top dead center (TDC) to bottom dead center (BDC). Answers For Thermodynamics Problems Answer for Problem # 1 Since the containers are insulated, no heat transfer occurs between the gas and the external environment, and since the gas expands freely into container B there is no resistance "pushing" against it, which means no work is done on the gas as it expands. What is the change in internal energy of the system? Water enters the condense at 30 C and leaves at 60 C. What is the temperature difference in F? 0
