Q. A hot body at temperature $T$ losses heat to the surrounding temperature $T_{s}$ by radiation. If the difference in the temperature is small then, the rate of loss of heat by the hot body is proportional to
A) $(T - T_{s})$
B) $\left( T - T_{s} \right)^{2}$
C) $\left( T - T_{s} \right)^{1/2}$
D) $\left( T - T_{s} \right)^{4}$
Explanation
The correct answer is Option A: $(T - T_{s})$.
