Question

solids on heating and on cooling​

Answer 1

Answer:

All three states of matter (solid, liquid and gas) expand when heated. The atoms themselves do not expand, but the volume they take up does. When a solid is heated, its atoms vibrate faster about their fixed points. ... An increase in temperature results in the expansion of the liquid which means it rises up the glass.Through grave sand's ring and experiment it can be proved that solids expand on heating and contract on cooling.
