We ASSUME constant volumes...and we convert temperatures to the absolute scale...

Explanation:

And so ${P}_{1} / {T}_{1} = {P}_{2} / {T}_{2}$...and we KNOW that $760 \cdot m m \cdot H g \equiv 1 \cdot a t m$...

And so...${T}_{2} = {P}_{2} \times {T}_{1} / {P}_{1}$

$= 3.71 \cdot a t m \times \frac{297.15 \cdot K}{\frac{713 \cdot m m \cdot H g}{760 \cdot m m \cdot H g \cdot a t {m}^{-} 1}}$

$= 1175 \cdot K$...
