Oxygen boils at $-183^{\circ} \mathrm{C}$. This temperature is approximately
  1. $215^{\circ} \mathrm{F}$
  2. $-297^{\circ} \mathrm{F}$
  3. $329^{\circ} \mathrm{F}$
  4. $361^{\circ} \mathrm{F}$

Solution

We know, $\frac{9 C}{5}=F-32$ $\begin{aligned} & \Rightarrow \quad F=C \times \frac{9}{5}+32 \\ & \Rightarrow \quad F=-183 \times \frac{9}{5}+32 \\ & =-297.4^{\circ} \mathrm{F} \approx-297^{\circ} \mathrm{F} \\ & \end{aligned}$
