MCQ
Maximum density of ${H_2}O$ is at the temperature  .......... $^oF$ 
  • A
    $32$
  • $39.2$
  • C
    $42$
  • D
    $4$

Answer

Correct option: B.
$39.2$
b
(b) Maximum density of water is at $4°C$

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