Heat – Notes
Matter In Our Surroundings – Inter Conversion of States of Matter
Inter conversion of states is the phenomenon of the change of matter from one state to another and back to original state, by altering the temperature.
The process where a solid changes to a liquid is called melting.
Latent heat of fusion is the amount of heat energy required to change 1kilograms of a solid into liquid.
The process where a liquid changes to gas as its boiling point is called vaporisation.
Latent heat of vaporisation is the amount of heat required to change a unit mass of liquid to gas at atmospheric pressure.
Evaporation is the process where a liquid changes into vapour at any temperature below its boiling point.
