Step 1
The formula is given by: \[ P = \sigma A T^4 \] where \( P \) is the power radiated, \( \sigma \) is the Stefan-Boltzmann constant, \( A \) is the surface area, and \( T \) is the absolute temperature. Show more…

The rate of emission of radiation of a black body at temperature $27^{\circ} \mathrm{C}$ is $E_{1}$. If its temperature is increased to $327^{\circ} \mathrm{C}$, the rate of emission of radiation is $E_{2} .$ The relation between $E_{1}$ and $E_{2}$ is (a) $E_{1}=24 E_{1}$ (b) $E_{2}=16 E_{1}$ (c) $E_{2}=8 E_{1}$ (d) $E_{2}=4 E_{1}$

The rectangular surface of area $8 \mathrm{~cm} \times 4 \mathrm{~cm}$ of a black body at a temperature of $127^{\circ} \mathrm{C}$ emits energy at the rate of $E$ per second. If the length and breadth of the surface are each reduced to half of its initial value, and the temperature is raised to $327^{\circ} \mathrm{C}$, the rate of emission of energy will become (a) $\frac{3}{8} E_{1}$ (b) $\frac{81}{16} E$ (c) $\frac{9}{16} E$ (d) $\frac{81}{64} E$
(a) If the Kelvin temperature of an object is doubled, its radiated power increases by (1) 2, (2) 4, (3) 8, (4) 16 times. Explain. (b) If its temperature is increased from $20^{\circ} \mathrm{C}$ to $40^{\circ} \mathrm{C},$ by how much does the radiated power change?
