Question

If the temperature of a body is raised by $5$% then the heat energy radiated would increases by

• A. $5$%
• B. $10$%
• C. $11.65$%
• D. $21.55$

Answer 1

The correct option is A $5$%

According to Newton's law of coding:

The rate of loss of heat of a body is directly proportional to the difference in temperature of the body and surrounding provided the difference in temperature is not more than ${40}^{o}C$

$\therefore$Rise in temperature $\alpha$ Heat energy radiation

$\therefore 5\%$ increase in heat energy radiation.
