Is CP - CV = R Always Correct? Big Myth in Thermodynamics | JEE NEET Class 11 Physics by S K Jha Sir

In this video, S K Jha Sir (Founder of Physics Classes, Kankarbagh, Patna) with 24+ years of IIT-JEE and NEET teaching experience reveals the real truth behind Mayer's Formula. Most students think CP - CV = R is always true, but in this class, we prove that this formula is completely CONDITIONAL and only valid under specific conditions for Ideal Gases. Learn why it changes for gram specific heat and different units.
