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

The temperature of a piece of iron is 27°C and it is radiating energy

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