Ideal Gas and Kinetic Theory
Ideal Gas and Kinetic Theory: Overview
In this topic, we will cover the properties of molecules and explain the kinetic theory of gases. Gas molecules travel at extremely high speeds and have high kinetic energy. Gases are made up of particles that are in continuous random motion.
Important Questions on Ideal Gas and Kinetic Theory
State and derive (a) Boyle’s law (b) Charles’ law and (c) Perfect gas law.
