# Water boils at 100°C. What is that temperature on the Kelvin scale?

Feb 24, 2016

$373 \text{K"~~"400 K}$

#### Explanation:

To convert temperature in degrees Celsius to Kelvins, add 273.15.

$\text{K="^@"C"+"273.15}$

$\text{K=100"^@"C"+"273.15"="373.15 K"="373 K}$ (rounded to a whole number)**

**The answer should also be rounded to $\text{400 K}$ because $\text{100"^@"C}$ has only one significant figure.
