Specific heat at constt. volume of an ideal gas

Click For Summary
SUMMARY

The specific heat at constant volume (cv) of an ideal gas is defined as temperature-independent by physicists, while engineers consider it temperature-dependent due to the behavior of real gases at low densities. This distinction highlights the differing definitions across disciplines regarding ideal gases. Understanding these definitions is crucial for accurate thermodynamic calculations and applications.

PREREQUISITES
  • Understanding of thermodynamics principles

The ans comes out (c) if I take specific heat at constt volume to be independent of temp.
Whether the specific heat is always temp. independent for an ideal gas??

Physicists define an ideal gas as a substance with a specific heat that is independent of temperature. Engineers define an ideal gas as the limiting behavior of a real gas at low density, such that its specific heat is dependent on temperature. Other disciplines, I don't know.
