Understanding the Molar Heat Capacity of an Ideal Gas

Click For Summary
SUMMARY

The discussion clarifies that for an ideal gas, the differential of the internal energy function is expressed as dU = n Cv dT, where Cv represents the molar specific heat at constant volume. This definition is crucial for understanding thermodynamic processes involving ideal gases. The distinction between molar heat capacity and specific heat is emphasized, confirming that Cv is indeed the molar heat capacity.

We know that for an ideal gas the differential of the internal energy function is:

dU = n Cv dT

But is Cv the molar heat capacity or not?
