Expansion of a gas in vacuum is called free expansion. Calculate the work done and the change in internal energy when 1 litre of ideal gas expands isothermally into vacuum until its total volume is 5 litre?

(–w) = pext (V2–V1) = 0 × (5 – 1) = 0
For isothermal expansion q = 0
By first law of thermodynamics
q = ΔU + (–w)
⇒ 0 = ΔU + 0 so ΔU = 0
