In an isochoric process the increase in internal energy is

Options

A. Equal to the heat absorbed
B. Equal to the heat evolved
C. Equal to the work done
D. Equal to the sum of the heat absorbed and work done

Answer

A

Explanation

For isochoric process `Delta V=0` so `q_(v)=Delta U` i.e., heat given to a system under constant volume is used up in increasing `Delta U`.
