Question

Define melting point?

Give Reasons:

Steam produces more severe burns as compared to boiling water.

Answer 1

The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid at atmospheric pressure.

The melting point of its solid form is the same as the freezing point of its liquid form, and depends on such factors as the purity of the substance and the surrounding pressure.

Steam will produce more severe burns than boiling water because steam has more heat energy thanwater due to its latent heat of vaporisation.
