1.

a)

A piston–cylinder assembly contains air, initially at 1.9 bar, 295 K, and a volume of 0.6 m3. The air undergoes a process to a state where the pressure is 1 bar, during which the pressure–volume relationship is pV = constant. Assuming ideal gas behavior for the air, determine the mass in kg.

b)

Argon contained in a closed, rigid tank, initially at 51.1°C, 2.1 bar, and a volume of 2.9 m3, is heated to a final pressure of 7.1 bar. Assuming the ideal gas model with k = 1.51 for the argon, determine the heat transfer, in kJ.

Can you plis solved and show me step by step this problem. Im having a hard time with this topic, thank you! If little notes can be provided or explanation can be given I would be really grateful, I really want to learn how to do it.
