(c) Energy radiated from a body $Q = A\varepsilon \sigma {T^4}t$
==> $\frac{{{Q_2}}}{{{Q_1}}} = {\left( {\frac{{{T_2}}}{{{T_1}}}} \right)^4}$ ==> $\frac{{{T_2}}}{{{T_1}}} = {\left( {\frac{{{Q_2}}}{{{Q_1}}}} \right)^{1/4}} = {\left( {\frac{{4.32 \times {{10}^6}}}{{2.7 \times {{10}^{ - 3}}}}} \right)^{1/4}}$
$ = {\left( {\frac{{16 \times 27}}{{27}} \times {{10}^8}} \right)^{1/4}}$$ = 2 \times {10^2}$
==>${T_2} = 200 \times {T_1} = 80000\,K$

- 1Two bottles $A$ and $B$ have radii $R_{A}$ and $R_{B}$ and heights $h_{A}$ and $h_{B}$ respectively, with $R_{B}=2 R_{A}$ and $h_{B}=2 h_{A}$. These are filled with hot water at $60^{\circ} C$. Consider that heat loss for the bottles takes place only from side surfaces. If the time, the water takes to cool down to $50^{\circ} C$ is $t_{A}$ and $t_{B}$ for bottles $A$ and $B$, respectively. Then, $t_{A}$ and $t_{B}$ are best related asView Solution
