Air confined to one side of a rigid container divided by apartition, as shown in Fig.2. The outer side is initiallyevacuated. The air is initially at p₁=5 bar,T₁=500 K, and V₁= 0.2m³. When the partition is removed, the air expands to fill the entirechamber. Measurements show that V₂=2V₁and p₂=p₁/4. Assuming the air behavesas an ideal gas, determine (a) the final temperature, in K, and (b)the heat transfer, kJ.
