- Calculate the maximum theoretical efficiency of a heat engine that operates with the hot steam temperature at 390 °C and the cool steam temperature at 230°C. Please give your answer in two decimals, NOT percentage. For example, efficiency of 0.62. Your Answer: AnswerOne mole of an ideal gas is used as the working substance of an engine operating in the cycle shown in the figure below. BC and DA processes are reversible adiabatic.a) Is the gas monoatomic, diatomic or triatomic?b) What is the efficiency and engine?As shown in the figure below, 1.50 moles of H, gas is contained in the left side of a container. The two sides of the container are separated by a valve, and both sides are equal in volume. The right side of the container is initially evacuated. Valve Họ Vacuum (a) The valve is then opened, allowing H, gas to stream into the right side. What is the entropy change of the gas from before the valve opened to after it has filled the entire container? J/K (b) Does the temperature of the gas change? Assume the container is so large that the hydrogen behaves as an ideal gas. The temperature does not change. The temperature increases. The temperature decreases.
