Question
The graph shows the variation of temperature (T) of one kilogram of a material with the heat (H) supplied to it. At O, the substance is in the solid state. From the graph, we can conclude that
is the melting point of the solid
- BC represents the change of state from solid to liquid
represents the latent heat of fusion of the substance
represents the latent heat of vaporization of the liquid
is the melting point of the solid
represents the latent heat of fusion of the substance
represents the latent heat of vaporization of the liquid
The correct answer is: represents the latent heat of fusion of the substance
Since in the region AB temperature is constant therefore at this temperature phase of the material changes from solid to liquid and (H2 – H(a) heat will be absorb by the material. This heat is known as the heat of melting of the solid.
Similarly in the region CD temperature is constant therefore at this temperature phase of the material changes from liquid to gas and (H4 – H(c) heat will be absorb by the material. This heat as known as the heat of vaporisation of the liquid
