$A$ metallic ball and a highly stretched spring are made of the same material and have the same mass. They are heated so that they melt. The latent heat required:

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

What is latent heat? Explain with an example.

Compared to a burn due to water at $100\,^{\circ}C$,a burn due to steam at $100\,^{\circ}C$ is:

What are fusion and melting point? On what does the value of melting point depend?

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 ........ $cal/g$.
