Define latent heat. Please answer
Answers
Answer :-
Latent heat :- Heat required to change solid into liquid or gas.
They are classified into :-
- Latent heat of fusion :- The amount of heat required to convert 1 kg of ice into water at 1 atmospheric pressure and at constant temperature of 0°C is called latent heat of fusion.
- Latent heat of vapourisation :- The amount of heat consumed when 1 kg of water at its boiling point 100°C and 1 atmospheric pressure into vapours is called latent heat of vapourisation.
Answer:
Explanation:
latent heat means hidden heat
when ice at 0 degree celcius is heated it first covert into water at 0 degree celcius after a definite time if u observe during this time there is no rise of the temperature of water or ice the heat absorbed is used to break the H2O molecules in ice to form water
similarly when water boils at 100 degree celcius it is converted into steam of temperature 100 degree celcius after a definite time..during this time there is no rise in temprature of water [water cant be heated more than 100 degree celcius as it converts into steam at this temperature]
the heat absorbed during this definite time is used to break the bonds of hydrogen and oxygen in water to convert it into steam
to be noted-since there is no rise or fall in the temperature due heat is utilized for bond formation or breaking this heat is present it is a kind of hidden heat that mans latent heat
hope it helps you
