Question
Consider the adiabatic compression of 5
kmol of air from 105 Pa to 3x105 Pa. Initial
temperature is 25 °C.
Calculate the required work, the change in
internal energy, the initial volume and the
finite volume.
Air is assumed to behave as an ideal gas.
Hint:
Use adiabatic relation for an ideal gas
between temperatures, presures and
volumes and/or the equation of state, the
first law of thermodynamics and the
equipartition theorem.
