When do I use C_p − C_v = R in Thermodynamics & Kinetic Theory, and what does it mean?

Mayer's relation between molar heat capacities.

C_p − C_v = R — Mayer's relation between molar heat capacities. Use it when: one mole of ideal gas. Always check the condition holds before plugging in numbers.

Key point

C_p − C_v = R
