1.
A hot body will radiate heat most rapidly if its surface is
2.
It is hotter for the same distance over the top of a fire than it is in the side of it, mainly because
3.
The ends of two rods of different materials with their thermal conductivities, radii of cross-sections and lengths all are in the ratio 1:2 are maintained at the same temperature difference. If the rate of flow of heat in the larger rod is 
, that in the shorter rod in 
will be
, that in the shorter rod in will be
