Specific Heat Capacity | Class 11 Physics | Kinetic Theory

Описание: Learn How Different Gases Store Heat — The Complete Guide to Specific Heat Capacity!
In this video, we dive deep into one of the most important concepts in Class 11 Physics — Specific Heat Capacity, a key topic from the chapter Kinetic Theory.
We begin by understanding what specific heat really means — how much heat energy a substance needs to raise its temperature — and why gases behave differently depending on their molecular structure.
You’ll then explore how monatomic, diatomic, and polyatomic gases store energy through different degrees of freedom — translational, rotational, and vibrational — and how this affects their specific heats at constant pressure (Cp) and constant volume (Cv).
We’ll also discuss the relation Cp – Cv = R, and how the ratio γ (gamma = Cp/Cv) plays a crucial role in thermodynamics and sound propagation.

📚 What You’ll Learn in This Video
