Question

Define:-

Melting
Liquefaction or condensation
Vaporization
Solidification or freezing
​

Answer 1

Answer:

Melting

Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point.

Liquefaction or condensation

Liquefaction refers to the change of phase from a gas to a liquid. Condensation refers to the change of phase from a gas to either a liquid or a solid. ... On cooling, the kinetic energy of the gas molecules decreases.

Vaporization

Vaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. ... If conditions allow the formation of vapour bubbles within a liquid, the vaporization process is called boiling. Direct conversion from solid to vapour is called sublimation.

Solidification or freezing

Solidification, also known as freezing, is a phase change of matter that results in the production of a solid. Generally, this occurs when the temperature of a liquid is lowered below its freezing point.

Hope it helps u..... ☺️☺️✌️

Answer 2

Answer:

melting is a state when solid changes to liquid when heat is provided.

liquefaction is a state when gaseous substance changes to liquid when heat is taken out

in vapourization liquid changes to gas.

freezing is a process in which liquid changes to solid when heat is removed
