A black body is at a temperature of `527^(@)C`, to radiate twice as much energy per second its temperature must be increased to

A

`921^(@)C`

B

960 K

C

678 K

D

400 K

Text Solution

Verified by Experts

The correct Answer is:
B
`(E_(2))/(E_(1))=(T_(2)^(4))/(T_(1)^(4))`
`therefore ((T_(2))/(T_(1)))^(4)=2`
`T_(2)=2^(1//4)T_(1)=1.19xx800K`
