Question

One mole of ideal gas expands freely at 310K from five litre volume to 10 litre volume. The value is

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
