Question

Water freezes at ________ degrees Fahrenheit (${}^{\circ }\text{F}$).

• A. $0{}^{\circ }\text{F}$
• B. $32{}^{\circ }\text{F}$
• C. $-1{}^{\circ }\text{F}$
• D. $100{}^{\circ }\text{F}$

Answer 1

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

The freezing point of water is $0{}^{\circ }\text{C}$ or $32{}^{\circ }\text{F}$. Using the formula for conversion,
$\text{F}-32=\frac{9}{5}(\text{C}-0)$
$\text{F}-32=0$
$\text{F}=32$
