Option 4 : None of the above

All the given statements are incorrect.

Evaporation is a type of process which occurs on the surface of the liquid. Hence the statement I is incorrect.
Evaporation takes place at the melting point, boiling point and at freezing point.
As the pressure is lowered melting point in water increases. Hence, statement II is incorrect.
Latent heat of vaporization is the amount of heat required to change the phase of a substance from liquid to gas without any change in temperature. Hence, statement III is incorrect
Specific latent heat of fusion is the amount of heat required to change the phase of a substance from solid to liquid at its melting point.

Which of the following option is correct about the Latent heat of vaporization Once the water has begun to boil, the temperature remains constant at 100°C until all the water has changed into steam. The burns caused by steam are much more severe than those caused by boiling water. This is because steam contains more heat, in the form of latent heat than boiling water.?
