If R = universal gas constant, the amount of heat needed to raise the temperature of 2 mole of an ideal monoatomic gas from 273K to 373K when no work is done
100R
200R
300R
150R
As we learnt in
Work done in isochoric process -
W = 0
- wherein
since
W = 0
and
Total internal energy -
- wherein
Change in internal energy
(Always)
is degree of freedom
When no work is done.
