A cylinder of volume 0.3 m³is filled with a monotomic ideal gas at a temperature of 299 K and a pressure of 10⁶Pa. A valve is opened to an evacuated cylinder, and the gas is allowed to expand rapidly into a total volume of 0.7 m³without exchanging heat with the walls.

By how much did the internal energy of the gas change?

What is the new temperature of the gas?

T_new =

By how much did the Helmholtz free energy,F, change?
