A black body at `27^(@)C` surrounds another black body at `-73^(@)C`. Calculate the net heat transfer per second per square meter of the body at higher temperature..

A black body at 27°C surrounds another at -73°C.Calculate the net heat transferred per square metre of the body at higher temperature.

Cooling is transfer of heat energy from the body at higher temperature to lower temperature.

The energy emitted per second by a black body at 1227^(@)C is E. If the temperature of the black body is increased to 2727^(@)C the energy emitted per second in the terms of E in the second case.

The energy that is transferred from a body at a higher temperature to a body at a lower temperature

If a black body is heated from 27 ^@C to 927 ^@C , then the ratio of the radiation emitted by the body at the two temperatures will be

One black body at temperature T is surrounded by another black body at temperate T_1(T_1ltT) . At T, the radiation emitted by inner blackbody per unit area per second is proportional to
