Vedclass · Answer

(C) In the heating curve,the horizontal regions represent phase changes where the temperature remains constant.$1$. In the region between $H_1$ and $H_2$,the temperature is constant at $T_1$. This indicates a phase change from solid to liquid. The heat absorbed during this process is $(H_2 - H_1)$,which is the latent heat of fusion.$2$. In the region between $H_3$ and $H_4$,the temperature is constant at $T_2$. This indicates a phase change from liquid to gas. The heat absorbed during this process is $(H_4 - H_3)$,which is the latent heat of vaporization.Therefore,option $(C)$ is correct because $(H_2 - H_1)$ represents the latent heat of fusion.
