An insulated rigid tank is divided into two compartments by a partition. One compartment contains 8 kg of oxygen gas at 42 ∘C and 100 kPa, and the other compartment contains 4 kg of nitrogen gas at 20 ∘C and 180 kPa. The partition is then removed and the two gases are allowed to mix.   Part A Determine the mixture temperature after equilibrium has been reached. Express your answer to four significant figures. Part B Determine the mixture pressure after equilibrium has been reached. Express your answer to five significant figures and include the appropriate units.
