The rate of radiation of a black body at...

The rate of radiation of a black body at 0° C is E . The rate of radiation of this black body at `273^(@)C` will be

A

16 E

B

8 E

C

4 E

D

E

Verified by Experts

The correct Answer is:

A

Since, `E prop T^4`
`implies (E_1)/(E_2)=((T_1)/(T_2))^4 =((273+0)/(273+273))^4 implies E_2 = 16 E`
