Why are the winds coming from the sea cool in summer?

Which of the substances $A, B$,or $C$ has the highest specific heat? The temperature-time graph is shown.

The specific heat capacity of a substance is temperature dependent and is given by the formula $C = kT$,where $k$ is a constant of suitable dimensions in $SI$ units,and $T$ is the absolute temperature. If the heat required to raise the temperature of $1 \ kg$ of the substance from $-73^{\circ} C$ to $27^{\circ} C$ is $nk$,the value of $n$ is. . . . . . [Given: $0 \ K = -273^{\circ} C$.]

The quantities of heat required to raise the temperature of two solid copper spheres of radii $r_{1}$ and $r_{2}$ $(r_{1} = 1.5 r_{2})$ through $1 \ K$ are in the ratio:

$A$ substance is cooled at a constant power. Its temperature vs time graph is shown. The value of $S_{solid} : S_{liquid} : S_{gas}$ is:

The heat energy released by water of mass $2 \,kg$ when it is cooled by $10^{\circ} C$ is (Specific heat capacity of water $= 4200 \,J \,kg^{-1} \,K^{-1}$) (in $\,J$)
