Whose specific heat is high? Sand or water?

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:

On what does the value of heat capacity depend?

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

$50 \text{ g}$ of copper is heated to increase its temperature by $10^{\circ} \text{C}$. If the same quantity of heat is given to $10 \text{ g}$ of water,the rise in temperature is (specific heat of $\text{Cu} = 420 \text{ J kg}^{-1} {}^{\circ} \text{C}^{-1}$ and specific heat of water is $4200 \text{ J kg}^{-1} {}^{\circ} \text{C}^{-1}$) (in $^{\circ} \text{C}$)

Why is water used in a rubber bag for fomentation on the body?
