1.	DU = dQ is a valid for-(a) Adiabatic process(b) Isothermal process(c) Isobaric process(d) Isochoric process
Answer» 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

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

Answer»

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
