1) In an adiabatic process, by what factor must a diatomic gas be compressed so that its temperature increases from 20C to 450C?

2) A sample of 0.20 moles of ideal diatomic gas at 320 K undergoes an isothermal expansion of 2 to 8 . Make a P V diagram with the appropriate units. Calculate the work done by the gas during the expansion. What will have been the heat absorbed/released by the gas? Calculate the change in internal energy.
