What is the difference between Cp and Cv is equal to?


The temperature of a body increases as heat is consumed by it. And as heat escapes, the temperature drops. The total kinetic energy of the particles that make up an object is measured by the temperature of that object. As a consequence, when heat is absorbed by an object, it is converted into the kinetic energy of the particles, causing the temperature to rise.

  • The molar heat capacity C, at constant pressure, is represented by CP.
  • At constant volume, the molar heat capacity C is represented by CV.

Relationship between Cp and Cv

CP = CV + R

Cp – Cv = R

The value of R is 8.314 JK-1mol-1
