Question

dU = dQ is a valid for-
(a) Adiabatic process
(b) Isothermal process
(c) Isobaric process
(d) Isochoric process​

Answer 1

Answer:

(d) Isochoric

Explanation:

In isochoric process the volume of the system is remain constant

v = constant

dv = 0 _______(1)

Now, According to the first law of thermodynamics

du = dq - dw

we know dw = pdv

Therefore

du = dq - pdv

from =n(1) we have

du = dq

Hence proved
