4.diffusion
5.melting point
6.boiling point
plzz solve the problem fast it's argent ​

Answer 1

Answer:

1. the changing phase of liquid to vapour is called vaporisation
2. it is revers of vapourisation the conversion of vapour or gas in liquid
3. when solid changes directly in gas
4. the movment of substance from lower concentration to higher consentration
5. the state at which the solid melts
6. the state at which the liquid turns to vapour

Answer 2

1 Vaporisation

When a chemical or element is converted from a liquid or solid to a gas, this is the phenomenon which we called vaporisation.

2 Condensation

Condensation is the process by which water vapour changes in the air into liquid water is known as condensation.

3 Sublimation

When a solid turns into a gas without first become liquid, that is called sublimation.

4 Diffusion

The phenomenon in which the substance move from an area of high concentration to an area of low concentration.

5 Melting point

The temperature at which a solid melts to become a liquid at the atmospheric pressure is called its melting point.

6 Boiling point

The temperature at which a liquid starts boiling at the atmospheric pressure is known as boiling point.
