Question

Oxygen boils at $-183{}^{\circ }C$ . This temperature, on the Fahrenheit scale is

• A. $-\text{297.4}{}^{\circ }F$
• B. $-{\text{253.6}}^{\circ }F$
• C. $-{\text{342.6}}^{\circ }F$
• D. $-{\text{225.3}}^{\circ }F$

Answer 1

Answer: (A)

Using $\frac{C}{5}=\frac{F-32}{9}$
$-\frac{183}{5}=\frac{F-32}{9}$
$F-32=-\frac{183\times 9}{5}=-329.4$
$F=-329.4+32=-297.4$
