2 mole of an ideal gas at 27^(@)C expand...

2 mole of an ideal gas at `27^(@)C` expands isothermally and reversibly from a volume of 4 litre to 40 litre. The work done (in kJ) by the gas is :

A

5200 J

B

15600 kJ

C

52 kJ

D

5267 .6 kJ

Text Solution

Verified by Experts

The correct Answer is:
A
`intdw=-intP.dV`
`implies w_("rev")=-int6.V^(2)dV`
`=-6[(V_(2)^(3))/(3)-(V_(1)^(3))/(3)]"bar."m^(3),`
`w=-5200 " kJ"`
so, work done by the gas is 5200 kJ.
