In a thermodynamic process, pressure of fixed mass of a gas is changed in such a manner that the gas releases
of heat and
of work is done on the gas. If initial internal energy of the gas was
, what will be final internal energy?
Text Solution
Verified by ExpertsThe correct answer is:
B
Here, heat release by gas, 
Work done on gas, 
Here, heat released by gas and work done on gas are taken negative.
We know that, first law of thermodynamics,

Now, given that, initial internal energy of gas,
