The graph signifies
Adiabatic expansion of a gas
Isothermal expansion of a gas
Change of state from liquid to solid
Cooling of a heated solid
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
What is the effect of pressures on boiling point of water ?
Why the cooking is faster in pressure cooker ?
The figure given below shows the cooling curve of pure wax material after heating. It cools from $A$ to $B$ and solidifies along $BD$. If $L$ and $C$ are respective values of latent heat and the specific heat of the liquid wax, the ratio $L/C$ is
