Evaporation 

*Evaporation: Change of a liquid into vapours at any temperature below its boiling point is called Evaporation.

Factors affecting evaporation:

*An increase of surface area: If the surface phenomenon. If the surface area is increased, the rate of evaporation increases. for Ex- While putting clothes for drying up we spread them out.

*An increase of temperature: With the increase of temperaturte, more number of particles get enough kinetic energy to go into the vapour state.

*A decrease in huminity: Huminity is the amount of water vapour present in the air. The air around us cannot hold more than a definite amount of water vapour at a given temperature. If the amount of water in the air is already high the rate of evaporation decreases.

*An increase in wind speed: Clothes dry faster on a windy day. With the increase in wind speed, the particles of water vapour move away with the wind.

*Condensation: The process in which a gas on cooling turns into a liquid at a specific temperature is called Condensation.

*Vaporisation: The process in which a liquid on heating changes into gas is called Vaporisation.

*Solidification: The process in which a liquid on cooling changes into solid is called Solidification.

*Fusion: The process in which a solid on heating changes into liquid then it is called Fusion.

*PLASMA: The state consists of super energetic and super excited particles. These particles are in the form of ionised gases . The fluorescent tube and neon sign bulbs consists of plasma.

*BOSE EINSTEIN CONDENSATE: Indian physicist Satyendra Nath Bose made a study regarding the fifth state of matter. Based on his study, Albert Einstein predicted a fifth state of matter called the Bose- Einstein Condensate.

*The Bose- Einstein Condensate or BEC is formed by coling a gas of extremely low density to super low temperatures.
