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
$L_f > L_v,S_l = S_s$
$L_f < L_v,S_l > S_s$
$L_f > L_v,S_l < S_s$
$L_f = L_v,S_l > S_s$
The portion $AB$ of the indicator diagram representing the state of matter denotes
On a hot day, placing a cup full of ice water on the table heats up as cup of hot tea on the same table cools down. write the reason.
