If the temperature of a black body increases from (7^ C ) to (287^ C ) then the rate of energy radiation increases by

Step-by-step solution

The energy radiated per unit time by a black body at absolute temperature (T ) is given by (H=A T^4 ). where (A ) is the area of a black body or ( H^ H = [(287+273) K ]^4 [(7+273) K ]^4 = [ 560 280 ]^4=16 )
