Question
What will be the increment in heat energy radiated when the temperature of hot body is raised by $5 \%$ ?(a) $5 \%$(b) $6 \%$(c) $11.65 \%$(d) $21.55 \%$
Step 1
If $T$ is the initial temperature and $dT$ is the change in temperature, then the change in heat energy $dQ$ is given by: \[dQ = 4T^3dT\] Show more…
