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