Radiation energy corresponding to the temperature T of the sun is E. If its temperature is doubled, then its radiation energy will be :

If temperature becomes double, the emitted radiation will be :

If temperature becomes double, the emitted radiation will be :

The temperature of a piece of iron is 27^(@)C and it is radiating energy at the rate of Q kWm^(-2) . If its temperature is raised to 151^(@)C , the rate of radiation of energy will become approximately

A black body radiates energy at the rate of E W//m at a high temperature TK . When the temperature is reduced to (T)/(2)K , the radiant energy will b

A black body radiates energy at the rate of E W//m at a high temperature TK . When the temperature is reduced to (T)/(2)K , the radiant energy will b

A body radiates energy 5 W at a temperature of 127^(@)C . If the temperature is increased to 927^(@)C , then it radiates energy at the rate of
