Question

Does heat increases the rate of sublimation ? ​

Answer 1

Answer:

• Sublimation is the process in which a Matter of solid state directly changes into gaseous state without passing through the liquid state.
• Sublimation process requires a particular temperature to occur.
• Some amount of heat is required to convert the solid state into liquid state
• So we infer that the rate of sublimation increases with the increase in heat .
• This heat is known as latent heat of sublimation.

Answer 2

Answer:-

Yes, the statement is correct.

Sublimation :- It is the process in which a solid is directly converted in to gaseous state when heating is known as sublimation.

The substance which undergoes sublimation is called sublime substance.

Example :- Camphor, Ammonium chloride, Naphthalene, etc.

In the process of sublimation the solids absorbs enough energy that its get directly converted in to gaseous states without get changed to liquids state.

As the sublimation ocurs at particular temperatures.

But when the temperature of surrounding is increased the rate of sublimation also increases because the solids absorbs enough heat energy to overcome the force of attraction and gets converted in to vapours state.

In case of Dry ice also known as Solid carbon dioxide It is heated and it's get quickly converted in to white cloudy vapours state.

So, The heat increases the rate of sublimation more the heat increases more the solids absorbs it and more quickly it changes in to vapours state.
