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