Which of these expands the most on heating solids liquids or gases? ›

Gases expand much more than the liquids and the solids. Like liquids, the gases do not have a definite shape, so they also have only the cubical expansion.

On applying heat to these different states of matter, they all expand. When heat is added, the molecules gain energy and vibrate and force other molecules to move apart. This expansion is minimum in solid compared with liquid and gases.

Melting occurs when a solid is heated and turns to liquid.

The higher the attraction between the molecules, the higher will be its expansion. As this attraction is the most in solids and the least in gases, solids expand the least and gases expand the most on being heated.

As heat energy increases in a substance, the molecules move faster and move greater distances. The forces the molecules to spread out, giving each other the necessary room to move. This expansion is witnesses in all three states of matter but solids expand less than liquids and liquids expand less than gases.

Solids have lower coefficient of cubic expansion than liquids hence expand lesser than liquids. Explain why gases expand more than liquids and solids.

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.

All the three states namely solid, liquid and gases expand on heating. Solid expands very less as compered to liquid and gases. Gases expands much more than liquid and solids. This happens because intermolecular force of attraction is very strong in solids, intermediate in liquids and very weak in case of gases.

The latent heat of fusion is required to convert a solid to liquid in phase change while latent heat of vaporization is required to change liquid to gaseous state.

Bubbles of water vapor are formed in the boiling water. This happens as particles of liquid water gain enough energy to completely overcome the force of attraction between them and change to the gaseous state. The bubbles rise through the water and escape from the pot as steam.

Why do liquids expand more than solids when heated? ›

As molecules in liquids are less tightly packed so they expand more than solids on heating.

On heating, solids and liquids expands in terms of size and volume. This is because on heating, their molecules or particles gain energy and become more active. Hence they start to move around quickly thereby increasing the size.

liquid hydrogen – 1 to 850. liquid oxygen – 1 to 860. neon – Neon has the highest expansion ratio with 1 to 1445.

As molecules in liquids are less tightly packed so they expand more than solids on heating.

The expansion by heat in different lorms of matter, is exceedingly various. By being heated from 32 to 212 , 1000 cubic inches of iron become 1004 1000 " water " 1045 1000 " air " 1366 Gases are, therefore, more expansable by heat than matter in the other two conditions ot liquid and solid.

Explanation: The greater the attraction between the molecules, the smaller the expansion will be. Solids expand the least and gases expand the most when heated because the molecular attraction is greatest in solids and least in gases.

liquid hydrogen – 1 to 850. liquid oxygen – 1 to 860. neon – Neon has the highest expansion ratio with 1 to 1445.
