Which of the following statements are correct for latent heat?
Which of the following statements are correct for latent heat?
The correct options are
A Latent heat of fusion is the heat energy that is absorbed by solid without showing any rise in temperature.
B Latent heat of vaporisation is the heat energy that is absorbed by liquid without showing any rise in temperature.
Particles of ice have strong attractive forces which have to be broken to convert it into liquid (or vapour). While supplying heat to melt ice, some amount of heat energy is utilized to break the attractive forces between the particles. This is known as the latent heat of fusion and during this time, there will not be a rise in temperature of the substance. Similarly, while supplying heat to boil water, some amount of heat energy is utilized to break the attractive forces between the particles. This is known as the latent heat of vaporization and during this time, there will not be a rise in temperature of the substance.
