Hello everyone, welcome to class 9th chemistry series. in this video, we will learn about the state of matter, class 9 chemistry. This chapter is a significant chapter for exam perspective as well as learning upcoming chapters of chemistry. In this video, I taught you about matter, state of matter, solid, liquid, gas, properties of solid, liquid and gas, change of state of matter, melting point, latent heat of fusion, boiling point, latent heat of vaporisation, sublimation, the difference between vaporisation and evaporation. I covered all the important topics asked in the the yearly exam. I tried my best to teach the concept mentioned above by heart. I hope you all will love this video and learn a lot.
