Question

On heating do all solids change from the solid state to the liquid state? If no then explain with the help of an example.​

Answer 1

Answer:

No, all substances don't change from solid to liquid and then to gas on heating. Some substances directly change into gaseous state when it is heated. They are called sublime. For example: camphor.

Usually when solids are heated they melt and becomes liquid. Then on further heating the liquid boils to form a gas. When we keep a piece of ice in a dish it melts and the water so formed evaporates after sometime. However there are some substances which on heating directly turn into gases from solids. camphor iodine crystals and solid carbon dioxide are such substances. Such substances are called sublimatory substances and this process of conversion is known as sublimation.
