Question

Question 1:
The value of specific heat of an ideal gas, with rise in temperature.
a) Increases
b) Decreases
c) is independent
d) None of these above​

Answer 1

Answer:

Specific Heat for an Ideal Gas at Constant Pressure and Volume. This represents the dimensionless heat capacity at constant volume; it is generally a function of temperature due to intermolecular forces. For moderate temperatures, the constant for a monoatomic gas is cv=3/2 while for a diatomic gas it is cv=5/2 (see ).

Answer 2

Answer:

Ideal monoatomic gas have only translational degrees of freedom. So, for monoatomic gases, C

v

is independent of temperature, and for rest all gases C

v

increases with increase in temperature.

So here for Ar, C

v

is independent of temperature.
