Chapter 8 Numericals Solution | 8.1 to 8.5 | 9th Class Physics | Physics | 9th Class اردو / हिंदी

In today lecture, we are going to solve the numerical problems of chapter 8 (Thermal Properties of Matter) of 9th class physics. This is the 1st part of this chapter in which we will solve first five numerical such as from 8.1 to 8.5 from the exercise. We provide most easy and authentic method to solve these problems. Hope you like it.
