Stefan's Law || Newton's Law, Average Rate OF Cooling

The thermal radiation emitted by a body per second per unit area is (DeltaH)/(A Deltat)=kT^(4) . If sigma is Stefan's constant, then body

Statement-1 : When temperature of a black body is doubled, energy radiated/sec/area becomes 16 times. Statement-2 : This is per Stefan's law.
