Question

The specific heat of an ideal gas is

• A. Proportional to T
• B. Proportional to $T^{2}$
• C. Proportional to $T^{3}$
• D. Independent of T

Answer 1

Answer: (D)

Independent of T

Answer 2

According to the equilibrium theorem, the molar heat capacities should be independent of temperature. However, variations in C_V and C_P are observed as the temperature changes. At very high temperatures, vibrations are also important and that affects the values of C_V and C_P for diatomic and polyatomic gases. Here in this question according to given information (4) may be correct answer.
