Question

When 150 litres of a gas enclosed in a vessel maintained a pressure of 1616 my is allowed to expand e
800 litres under constant temperature conditions, what would be it's pressure​

Answer 1

Given,
Pressure, P=2×10
5
pa
Change in volume, ΔV=150−50=100litre=0.1m
3

Work done =PΔV=2×10
5
×0.1=2×10
4
kJ
Hence, work done is 2×10
