Problem 3 (20 points) Two rigid chambers are connected with a pipe and a valve. Chamber A has 0.5kg air at 200kPa and 300K, and Chamber B has 0.75kg air at 100kPa and 400K. The valve is opened, and the air comes to a single uniform state with the heat loss of 18.75kJ. Assuming that the air is ideal gas with the gas constant R=0.287kJ/kgK, please determine the following: (a) The final temperature (K). Do not try to interpolate but just use the closest value when tables are used. (b) The final pressure ( kPa)
