Question

typical temperatures
212°f water boils
98.6°f body temperature
70°f room temperature
32°f freezing point of water
0°f cold day
-40°f very cold day
the basic unit of temperature in the metric system that is used internationally is the degree celsius. (°c).
useful conversion formulas:
°c to °f multiply by 9, then divide by 5, then add 32
°f to °c deduct 32, then multiply by 5, then divide by 9 water freezes at ____ °c
water boils at ____ °c
normal human body temperature is ____ °c.

Explanation:

Step1: Convert freezing - point of water

Given the formula for converting $^{\circ}F$ to $^{\circ}C$: $C=\frac{(F - 32)\times5}{9}$. For the freezing - point of water, $F = 32$. Substitute $F = 32$ into the formula: $C=\frac{(32 - 32)\times5}{9}=0$.

Step2: Convert boiling - point of water

For the boiling - point of water, $F = 212$. Substitute into the formula $C=\frac{(F - 32)\times5}{9}=\frac{(212 - 32)\times5}{9}=\frac{180\times5}{9}=100$.

Step3: Convert body temperature

For body temperature, $F = 98.6$. Substitute into the formula $C=\frac{(F - 32)\times5}{9}=\frac{(98.6 - 32)\times5}{9}=\frac{66.6\times5}{9}=37$.

Answer:

Water freezes at 0 $^{\circ}C$.
Water boils at 100 $^{\circ}C$.
Normal human body temperature is 37 $^{\circ}C$.
