Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Dear student,
Greetings!!
According to the first law of thermodynamic :
q = dE + W (for expansion V increase)
W = -pdV ( for compression V decrease)
If V is constant then,
dV = 0
So q = dE (W = 0)
So the formula given in this derivation is correct.
Thank you for asking your query.
