NCERT Class 11 Physics – Kinetic Theory
The chapter Kinetic Theory in NCERT Class 11 Physics explains the microscopic behavior of gases and their macroscopic properties. It is based on the kinetic molecular model, which considers gases as a large number of small particles in constant random motion. The chapter links pressure, volume, and temperature of a gas to the motion of its molecules, forming the foundation of the ideal gas equation.
Students learn about kinetic energy of gas molecules, root mean square speed, and the distribution of molecular speeds. The concept of degrees of freedom and the law of equipartition of energy is also introduced, explaining how energy is shared among translational, rotational, and vibrational modes.
By practicing NCERT examples and exercises, learners develop a clear understanding of gas behavior, strengthen problem-solving skills, and prepare effectively for board exams, JEE, and NEET, making this chapter essential in Class 11 Physics.
