Question

write two applications each of thermal expansion of solids.discuss in detail​

Answer 1

solids are the particles which have more attractive they are attached to each other.their particles have less intermolecular force there is no space.paricles are in motion.they can not be compressed.they can not flow.they can broke on high pressure.

Answer 2

The two examples of the application of thermal expansion of solids are :-
