5kg of r-134a at 300 kpa fills a rigid container whose volume is 44 l. (a) identify two independent intensive properties and thus show that the system state is well defined. what is the description of the state of the r-134a? (b) determine the temperature and total internal energy in the container. the container is now heated until the pressure is 600 kpa. (c) sketch a diagram of the process indicating the system and direction of all relevant energy flows. list all your assumptions. (d) fill in the blank: "the heating process occurs under iso conditions." (e) after heating, has the state description changed from the initial state? explain. (f) determine the temperature and total internal energy when the heating is completed.
