Is the specific heat of water and ice the same? Give their values.

$A$ small electric heater is used to heat $200 \,g$ of water. The time required to bring all this water from $40^{\circ} C$ to $100^{\circ} C$ is $200 \,s$. If the specific heat of the water is $4200 \,J \,kg^{-1} \,K^{-1}$, then the power supplied by the heater is: (in $\,W$)

The amount of heat required to raise the temperature of a body by $1^oC$ is called its

During illness,an $80 \, kg$ man had a fever of $102.2^\circ F$ instead of his normal body temperature of $98.6^\circ F$. Assuming that the human body is mostly water,how much heat is required to raise his temperature by that amount in $kcal$?

The ratio of the heat capacities of two bodies is $1:4$. If the rate of heat loss is the same for both bodies under similar environmental conditions,then the ratio of the rate of fall of their temperatures is:

$50 \text{ g}$ 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 $^{\circ} \text{C}$)
