6. Write down three problems caused by expansion or contraction. How are these problems overcome​

Answer 1

Answer:

when substances expand or contract, their particles stay the same size. it is the space between the particles that changes : the particles in a solid vibrate more when heated and takes up more room.

the particles in a liquid move around each other more, when it is heated which takes up comparatively less room
