Air is confined to one side of a rigid container divided by a Removable partition partition, as shown in the figure. The other side is initially evacuated. The air is initially at py = 5 bar, 7, = 500 K, and Air 1/7 =0.2 m'. When the partition is removed, the air expands to Initially: V = 0.2 m P1 =5 bar Vacuum fill the entire chamber. Measurement show that V2 = 21, and 7 = 500 K p2 = p//4. Assuming the air behaves as an ideal gas, determine a. the final temperature, in K; and b. the heat transfer, k.J. Va = 2V Finally
