Question

1.what is meant by melting point and boiling point?
2.what is meant by boiling ?
3.what is meant by latend heat of vapourization and also latend heat of fusion?
4.what is meant by freezing?

please explain breifly

Answer 1

1.the temperature at which water starts boiling is called the boiling point. it's 100 degree.
the temperature at which water startes melting is called the melting point.
2.the process of heating water is called boiling.
4.the process of decreasing of temperature of water causes freezing .

Answer 2

1. boiling point .The temperature at which a given material changes from a liquid to a gas.
Melting point- the temperature at which a soild starts turning into liquid.
2.Boiling Definition: a phase transition from the liquid state to the gas state, usually occurring when a liquid is heated to its boiling point.
3.In the case of the latent heat of fusionit is the heat required to change a substance from a solid (ice) to a liquid (water) or vice versa while the latent heat of vaporization from a liquid (water) to a gas (steam) or vice versa.
4.Freezing, or solidification, is a phase transition in which a liquid turns into a solid when its temperature is lowered below its freezing point.
