Steam at $100\,^{\circ}C$ is more dangerous than the same mass of water at $100\,^{\circ}C$ because the steam

$A$ substance of mass $m \ kg$ requires a power input of $P \ W$ to remain in the molten state at its melting point. When the power is turned off,the substance completely solidifies in time $t \ s$. The latent heat of fusion of the substance is

The graph shown in the figure represents the change in the temperature of $5 \, kg$ of a substance as it absorbs heat at a constant rate of $42 \, kJ \, min^{-1}$. The latent heat of vaporization of the substance is ......... $kJ \, kg^{-1}$.

The portion $AB$ of the cooling curve representing the state of matter denotes:

Why do we get burnt more by steam than by boiling water at the same temperature?

Boiling water is changing into steam. At this stage,the specific heat of water is
