Question

1. Suppose a gas expands by 500ml aganist a pressure of 1.20 atm and no heat is exchanged with the surrounding during the expansion. How much work is done in the expansion

Answer 1

$Work=−P_{ext} × volume_{change}$

$500ml=0.5litres$

$Work =−1.20 ×0.5=−0.6 litre/atm$

$=−0.6×101.328J=−60.7968J$
