Latent heat of $1\,gm $ of steam is $536 \,cal/gm,$ then its value in $joule/kg$ is
$2.25 \times {10^6}$
$2.25 \times {10^3}$
$2.25$
None
The graph shows the variation of temperature $(T)$ of one kilogram of a material with the heat $(H)$ supplied to it. At $O,$ the substance is in the solid state. From the graph, we can conclude that
What is vapourization ? What is normal boiling point ?
When $M_1$ gram of ice at $-10\,^oC$ (specific heat $= 0.5\, cal\, g^{-1}\,^oC^{-1}$) is added to $M_2$ gram of water at $50\,^oC$, finally no ice is left and the water is at $0\,^oC$. The value of latent heat of ice, in $cal\, g^{-1}$ is
A given mass $m$ of a hypothetical solid is supplied with heat continuously at a constant rate and the graph shown in the adjacent figure is plotted. If $L_f$ and $L_v$ are latent heats of fusion and latent heats of vaporization and $S_l$ and $S_s$ are specific heats of liquid and solid respectively. It can be concluded that
A closed bottle containing water at $30°C$ is carried to the moon in a space-ship. If it is placed on the surface of the moon, what will happen to the water as soon as the lid is opened
