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

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

$A$ block of ice with mass $m$ falls into a lake. After impact,a mass of ice $m/5$ melts. Both the block of ice and the lake have a temperature of $0^{\circ}C$. If $L$ represents the latent heat of fusion,the minimum distance the ice fell before striking the surface is

An ice cube at temperature $-20^oC$ is kept in a room at temperature $20^oC$. The variation of temperature of the body with time is given by
