Question

three litres of an ideal gas at a pressure of 5 atmosphere expands freely at constant pressure until the volume is 8 litres . how much is the work done in expansion ​

Answer 1

Answer:

2 litres of an ideal gas : V1 = 2 litres

P1 = 10 atms

T = constant

V2 = 10 litres

  =>  P2 = P1 V1 / V2 = 2 atm

work done =

This is the work done in expansion of the gas.  As the gas remains at the same temperature, there is no change in the internal energy.

So energy absorbed is = 3.2607 kJoules
