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
$L_f > L_v,S_l = S_s$
$L_f < L_v,S_l > S_s$
$L_f > L_v,S_l < S_s$
$L_f = L_v,S_l > S_s$
What is the main difference between $P \to T$ diagram of water and $C{O_2}$ ?
A solid cube having certain fixed melting and boiling points takes heat from some source.The variation of temperature $\theta$ of the cube with the heat supplied $Q$ is shown in the adjoining graph. The portion $BC$ of the graph represents the conversion of
A closed bottle containing water at $30^{\circ} C$ is open on the surface of the moon. Then,
$2\;gm$ of steam condenses when passed through $40gm$ of water initially at $25^oC.$ The condensation of steam raises the temperature of water to $54.3^oC.$ What is the latent heat of steam ........... $cal/g$
The temperature at which the vapour pressure of a liquid becomes equals to the external (atmospheric) pressure is its
