The latent heat of vaporization of a substance is always

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

An experiment takes $10\, minutes$ to raise the temperature of water in a container from $0\,^oC$ to $100\,^oC$ and another $55\, minutes$ to convert it totally into steam by a heater supplying heat at a uniform rate. Neglecting the specific heat of the container and taking the specific heat of water to be $1\, cal/g\,^oC$,the heat of vaporization according to this experiment will be ........ $cal/g$.

Latent heat of vaporisation of water is $22.6 \times 10^5 \ J \ kg^{-1}$. The amount of heat needed to convert $100 \ kg$ of water into vapour at $100^{\circ} C$ is

$A$ block of ice at $-10^{\circ} C$ is slowly heated and converted to steam at $100^{\circ} C$. Which of the following curves represent the phenomenon qualitatively:

During an experiment,it takes $10 \text{ minutes}$ to raise the temperature of water from $0 \text{ °C}$ to $100 \text{ °C}$,and then it takes another $55 \text{ minutes}$ for the water to completely convert into steam. The value of the latent heat of vaporization is ....... $\text{cal/g}$.
