$\Large{\underline{\underline{\red{\tt{\purple{\leadsto } Question:-}}}}}$

Liquid changes to gas by increasing which energy?

• a. Electrical energy
• b. Kinetic energy
• c. Potential energy.

$\Large{\underline{\underline{\red{\tt{\purple{\leadsto } AnsweR:-}}}}}$

Liquid changes to gas by increasing the Kinetic energy. This is done by providing heat energy to the liquid .On doing so the kinetic energy of the particle increases as a result it helps in breaking the forces of attraction between the molecules.

The process of changing liquid to gas is known as vaporization.

➳ BOILING POINT :

The point of temperature at which the vapour pressure of the liquid becomes equal to the atmospheric pressure is known as boiling point.

On adding impurities the boiling point decreases.

➳ EVAPORATION :

The change of liquid to its gaseous state below the boiling point is known as evaporation. It gives cooling effect.

➳ CONDENSATION :

The change of a gas to its liquid state is known as condensation.

➳ SUBLIMATION:

The direct change of solid to gaseous state without undergoing change in liquid state is known as sublimation. Camphor , Ammonium chloride , Dry Ice etc . undergo sublimation.

➳ FUSION :

The change of solid state to liquid state is known as fusion.

➳ CRITICAL TEMPERATURE :

The temperature above which the gas cannot be liquefied is known as critical temperature.

➳ TRIPLE POINT OF WATER :

The temperature at which all three States of water can exist is known as triple point of water
