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

$0.93 \, Wh$ of energy is supplied to a block of ice weighing $10 \, g$. It is found that:

Two substances $A$ and $B$ of equal mass $m$ are heated at a uniform rate of $6 \, cal \, s^{-1}$ under similar conditions. $A$ graph between temperature and time is shown in the figure. The ratio of heat absorbed $H_A/H_B$ by them for complete fusion 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 ......... $kJ \, kg^{-1}$.

$A$ quantity of heat required to change the unit mass of a solid substance,from solid state to liquid state,while the temperature remains constant,is known as

Boiling water is changing into steam. The specific heat of boiling water is
