Question

What's the specific heat at constant volume?
Please tell me the answer with explanation​

Answer 1

Answer:

Specific heat at constant volume represents the heat supplied to a unit mass of the system to raise its temperature through 1K, keeping the volume constant.

Explanation:

Since, V= Constant, dV = 0 and the work done by the system W = PdV = 0. The first law of thermodynamics says: Q = (dU+W) = (dU+PdV) = dU.

Answer 2

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 ).
