Two litres of an ideal gas at a pressure of 10 atm expands isothermally at 25 °C into a vacuum until its total volume is 10 litres. How much heat is absorbed and how much work is done in the expansion ?

(a) Two litres of an ideal gas at a pressure of 10 atm expands isothermally into a vacuum until its total volume is 10 litres. How much heat is absorbed and how much work is done in the expansion? (b) Consider the same expansion, but this time against a constant external pressure of 1 atm. (c) Consider the same expansion, to a final volume of 10 litres conducted reversibly.
