Thermal expansion

Thermal Expansion of Solids , Liquids and Gases

When matter is heated it expands and when cooled it contracts.

According to the kinetic theory the molecules of solid and liquids are in constant vibration.

When heated, they vibrate faster and force each other a little further apart. 

Expansion results , and this is greater for liquid , gases expand even more.

i was dying to understand that about bridges in the precautions of thermal expansion, couldn't find it anywhere on the internet. this really helped. but i still didn't get how does rollers at the other end work?

Equation -2 is wrong. E/t = V . I P = V I
