Question

When a solid is heated , it expands in length only. True or False​

Answer 1

solids expand this is true but not all the solids

Answer 2

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. The relative increase in the size of solids when heated is therefore small
