Question

The maximum density of water is at the temperature of ${39.2}^{\circ }F$ .

• A. 32°F
• B. 39.2°F

Answer 1

The correct option is A

32°F

Maximum density of water is at $4^{\circ }C$

Also $\frac{C}{5}=\frac{F-32}{9}\Rightarrow \frac{4}{5}=\frac{F-32}{9}$
$\Rightarrow F={39.2}^{\circ }F$
