Question
Problem 1: Textbook 9.2.3 Calculate the following quantities using the definition of enthalpy. Assume the air is an ideal gas, the heat capacities c₁ = 21 J/gmol.K, cp=cy + R, where R is the gas constant. Use tank volume V = 10 m³. *9.2.3. A rigid tank contains air at 400 kPa and 600°C. As a result of heat transfer to the surroundings, the temperature and pressure inside the tank drop to 100°C and 200 kPa, respectively. Calculate the work done during this process. a) The total heat transfer AQ in joules (3 points) b) The work done to the system or surroundings AW (3 points) c) The internal energy change AU (3 points) d) The enthalpy change AH (3 points)
