Question

In an isochoric process, the increase in internal energy is equal to: (A) the sum of heat absorbed and work done (B) the work done (C) heat absorbed (D) heat evolved

Tardigrade Admin · Accepted Answer

In an isochoric process, Δ V=0, hence, work done P Δ V=W=0. So, Δ E=q+0. Hence, the increase in internal energy will be equal to heat absorbed by the system.

Q. In an isochoric process, the increase in internal energy is equal to:

the sum of heat absorbed and work done

the work done

heat absorbed

heat evolved

In an isochoric process, $Δ V = 0$ , hence, work done $P Δ V = W = 0$ .
So, $Δ E = q + 0$ .
Hence, the increase in internal energy will be equal to heat absorbed by the system.
