Vedclass · Answer

(B) In a temperature-heat graph,the regions where the temperature remains constant (horizontal lines) represent phase changes,as the heat supplied is used as latent heat to change the state of the substance.$1$. The portion $AB$ represents the heating of the solid.$2$. The portion $BC$ is a horizontal line where the temperature is constant,representing the melting point of the solid. Thus,it represents the phase change from solid to liquid.$3$. The portion $CD$ represents the heating of the liquid.$4$. The portion $DE$ is another horizontal line representing the boiling point,where the liquid converts into vapour.$5$. The portion $EF$ represents the heating of the vapour.Therefore,the portion $BC$ represents the conversion of solid into liquid.

$A$ solid cube having certain fixed melting and boiling points takes heat from some source. The variation of temperature $\theta$ of the cube with the heat supplied $Q$ is shown in the adjoining graph. The portion $BC$ of the graph represents the conversion of
