Question

1 A gas expands from volume of 5 litere to 30 lit under a peessure of 1.5 atom Find W and V ,if 2000 cal of heat is supplied to system?​

Answer 1

Explanation:

Work = - Pext × volume change = - 1 × 0.5 = - 0.5 litre - atm = - 0.5 × 101.328J = - 50.664J 0.5litre - atm = - 0.5 × 24.20 = - 12.10cal

Answer 2

Answer:

Work=−P ext ×volumechange

=−1×0.5=−0.5 litre-atm

=−0.5×101.328J=−50.664J

0.5litre−atm=−0.5×24.20=−12.10cal
