All solids, on heating, first change to liquid and then to the gaseous state.

With decrease in heat, solids change to liquids and liquids change to gaseous state.

How does a liquid change into its gaseous state? Explain.

When a solid changes into liquid, the entropy

Fill in the blank spaces by choosing the correct words from the list given below: latent heat of fusion, melting point, steam, constant, latent heat of vaporisation. The amount of heat required to change 1 g of a liquid into its gaseous state without and rise in temperature is called specific ___________.

Assertion: On heating, a solid usually change to a liquid and the liquid on further heating change to the gaseous state. Reason : Arrangement of constituent particles is different in solid, liquid and gaseous state.

The point when water changes into gaseous state.

Write true or false for the following statements. When kinetic energy of the molecules of a liquid becomes more than the intermolecular forces then energetic molecules rapidly leave the liquid and change into the gaseous state.

A solid changes to a liquid on heating. Why?

On cooling, liquid changes into a solid state.

Than those which exist in the gaseous state. (c) The arrangement of particles is less ordered in the ... state. However, there is no order in the ..... state. (d)....... is the change of gaseous state directly to solid state without going through the ....... state. (e) The phenomenon of changes of a liquid into the gaseous state at any temperature below its boiling point is called ......
