Question

Describe one example each of expansion in solid, liquids​

Answer 1

Answer:

Expansion of solid:

Solids also undergo thermal expansion. Railroad tracks and bridges, for example, have expansion joints to allow them to freely expand and contract with temperature changes.

Expansion of liquid:

Heating of water expands it and converts it to gas

Expansion of gas:

When a balloon is partially inflated in a cool room it expands to full size when put in warm water. This all is due to thermal expansion. So, an increase in the dimension of a body due to an increase in temperature is thermal expansion
