Ace Federal Board (Class 10) Physics – Chapter 11: Thermal Transformation in one clear lesson. We explain the Kinetic Model of Matter and connect it to the real behavior of solids, liquids, and gases. With simple language and day-to-day examples, you’ll see how particle motion explains temperature, heat, density, diffusion, and phase changes. changing of state of Matter In this video we will explains expansion in solids #linear thermal expansion 00:00 introduction 0:32 Thermal expansion 2:50 Thermal expansion in solid 4:22 linear thermal expansion 4:49 Increase in temperature 6:58 Original length of rod 7:59 Nature of rod 9:52 Derivation of formula
