📘 Lecture 4 – Thermodynamics & Thermochemistry Series by Krishna Kumar Sah (ChembyKKSir)

Описание: 📘 Lecture 4 – Thermodynamics & Thermochemistry Series by Krishna Kumar Sah (ChembyKKSir)

In this lecture, I have explained the complete concept of Internal Energy in connection with the Kinetic Gas Theory and its Derivation.
You will learn how the Kinetic Energy of an Ideal Gas is directly related to its Absolute Temperature and how Internal Energy arises from molecular motion.

We have covered:
✅ Derivation of Kinetic Gas Equation from the postulates of the Kinetic Theory of Gases
✅ Concept of Pressure due to Molecular Collisions
✅ Mathematical proof that Kinetic Energy ∝ Absolute Temperature
✅ Relation between Kinetic Energy and Internal Energy for an Ideal Gas
✅ Concept that Internal Energy ≈ Kinetic Energy for an Ideal Gas
✅ Derivation showing Change in Internal Energy ≈ Change in Kinetic Energy (ΔU ≈ ΔKE)
✅ Physical significance of these relations in real and ideal gases

👉 This lecture connects Thermodynamics and the Kinetic Theory of Gases, providing a deep conceptual understanding for CBSE Class 11, JEE Main, JEE Advanced, and NEET aspirants.

If you find these topics confusing, this lecture will give you crystal-clear clarity through conceptual explanations and mathematical derivations.
