The average degree of freedom per molecule for a gas is 6. The gas performs 25 J of work when it expands at constant pressure. The heat absorbed by the gas is

A

`50 J`

B

`500 J`

C

`100 J`

D

`150 J`

Text Solution

Verified by Experts

The correct Answer is:
C
`W = P Delta V = n R Delta T = 25 J rArr Delta U = f/2 nR Delta T = 75 j rArr Delta Q = Delta U = W = 100 J`
