Physics Thermodynamics Mix MCQ (Single Correct)

The molar specific heat at constant volume of 3 moles of an ideal gas mixture is given by C V = aT, where a is constant and T is the absolute temperature. Which of the following is correct –

A
If the gas mixture undergoes adiabatic expansion, then change in its internal energy equals work done by it
B
The specific heat of gas mixture at constant pressure is independent of number of moles
C
Work done by gas mixture for all processes may depend upon number of moles
D
The degree of freedom of mixture depends upon absolute temperature

The correct answer is:
CHECK THE SOLUTION.

(b, c, d)

dU = – dW

Specific heat is independent of number of moles

For constant volume process, W = 0

C V = fR = At
