A black body of `127^(@)C` radiates heat at the rate of `5cal//cm^(2)`-second. At `527^(@)C`, the rate of heat radiated in the same units will be

A

32

B

48

C

64

D

80

Text Solution

Verified by Experts

The correct Answer is:
D
`(R_(2)/R_(1))=(T_(2)/T_(1))^(4)=16`
`thereforeR_(2)=16xx5=80` units
