Question

Chapter- Heat
Define the following-
a) Expansion in solids
b) Expansion in liquids
c) Expansion in gases​

Answer 1

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.

Expansion of liquids

The expansion of liquids is usually measured in a container. When a liquid expands in a vessel, the vessel expands along with the liquid. ... The expansion of the liquid relative to the container is called its apparent expansion, while the actual expansion of the liquid is called real expansion or absolute expansion

Thermal expansion in gases

Thermal expansion is large for gases, and relatively small, but not negligible, for liquids and solids. Linear thermal expansion is ΔL = αLΔT, where ΔL is the change in length L, ΔT is the change in temperature, and α is the coefficient of linear expansion, which varies slightly with temperature

Answer 2

Answer:

expansion is due to increase in space by heat

solid expand to form liguid less expensive

liquid expand to form gases more in comparison in solid

gases expand more in comperision of both solid and liquid

because of more space present in gas
