The ratio of rates of emission of heat by a black body at `367^@" at " 207^(@)C` is nealy

Compare the rates of emission of heat by a black body maintained at 727^@C and at 227^@C , if the black bodies are surrounded by an enclosure (black) at 27^@C . What would be the ratio of their rates of loss of heat.

The ratio of energy of emitted radiation of a black body at 27^(@)C and 927^(@)C is

Compare the rates of emission of heat by a blackbody maintained at 627 ""^(@)C and at 127 ""^(@)C , if the blackbodies are surrounded by an enclosure at 27 ""^(@)C . What would be the ratio of their rates of loss of heat?

Attempt any THREE : Compare the rates of loss of heat by a black body at 627^(@)C and 327^(@)C , if tempreature of surrounding is 27^(@)C .

Compare the rate of emission of heat by a black body at 327^@C with the rate of emission of heat of same body at 27^@C .

The ratio of energy of emitted radiation of black body at 27^(@)C and 927^(@) c is
