A black body is at `727^(@)C`. It emits energy at a rate which is proportional to

A

`(1000)^(4)`

B

`(1000)^(2)`

C

`(727)^(4)`

D

`(727)^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A

According to Stefan.s law
Rate of energy radiated `EpropT^(4)`
where T is the absolute temperature of a black body.
`thereforeEprop(727+273)^(4)orEprop[1000]^(4)`
