This is a short answer type question as classified in NCERT Exemplar

we know the speed of air v $\propto \sqrt[]{T}$

$\frac{v_{t}}{v_{o}} = \sqrt[]{\frac{T_{T}}{T_{o}}} = \sqrt[]{\frac{T_{T}}{273}}$

$\frac{V_{T}}{V_{o}} = \frac{3}{1}$

3/1 = $\sqrt[]{\frac{T_{T}}{T_{o}}} = \frac{T_{T}}{273} = 9$

T_T=273 $\times 9 = 2457 K$

=2457-273=2184 ^oC
