A body emits Q cal/`cm^(2)` of radiation at temperature `227^(@)C`. If the temperature of the body is raised to `727^(@)C`, then the amount of radiant enegy emitted will be

A

2Q

B

4Q

C

16Q

D

32Q

Text Solution

Verified by Experts

The correct Answer is:
C
`(E_(2))/(E_(1))=((T_(2))/(T_(1)))^(4)=((1000)/(400))^(4)=16`
`E_(2)=16Q`.
