If the temperature of a hot body is increased by `50%`, then the increase in the quantity of emitted heat radiation will be

Text Solution

Verified by Experts

The correct Answer is:
increase by 400 %
`E alpha T^(4)` and `therefore E alpha (1.5)^(4) T^(4) prop ((15)/(40))^(4) T^(4) prop ((3)/(2))^(4) T^(4) prop (31)/(16) T^(4) prop 5 T^(4)`
`(E'- E)/(E) xx 100 % = ((5 T^(4) - T^(4))/(T^(4))) xx 100 % = 400 %`
