Problem # p028

Ideal gas, conservation of energy

1 kg of air, initially at 600 kPa and 300 °C, undergoes an internally reversible, isothermal expansion to 300 kPa. Determine the work and heat for this process and sketch the process in a p-v and in a T-s diagram. Assume that the air can be treated as an ideal gas with constant specific heats.

cp/cv = 1.4         R = 0.287 kJ/(kg K)
