Question

What is the melting point of ice in Fahrenheit scale?

• A. ${40}^{\circ }F$
• B. ${32}^{\circ }F$
• C. ${52}^{\circ }F$
• D. ${72}^{\circ }F$

Answer 1

The correct option is B ${32}^{\circ }F$

We know melting point of ice in Celsius scale, $C=0^{\circ }C$
Let $F$ be the temperature in Fahrenheit scale
We also know that, $C=\frac{5}{9}(F-32)$
$\Rightarrow 0=\frac{5}{9}(F-32)$
$\Rightarrow F={32}^{\circ }F$
$\therefore$Melting point of ice in Fahrenheit scale is ${32}^{\circ }F$
