It's all about thermal expansion. In this video we will explore some day to day examples where we get to experience thermal expansion first hand. We will also peek into the atomic level and figure out the cause of this phenomenon.

How do you answer such questions? How do we assign a number to thermal expansion? In this video, we are going to explore how we can quantify thermal expansion of solids. We will start with linear expansion.

By the way changes in area is also called superficial expansion. The good thing is we don't need more physics. We can use whatever we learnt in linear expansion and just apply here. We will eventually define the area expansion coefficient.
