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
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
- A
${T_2}$ is the melting point of the solid
- B
$BC$ represents the change of state from solid to liquid
- C
$({H_2} - {H_1})$ represents the latent heat of fusion of the substance
- D
$({H_3} - {H_1})$ represents the latent heat of vaporization of the liquid
