Question

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

Answer 1

`373 "K"~~"400 K"`

Explanation:

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

`"K="^@"C"+"273.15"`

`"K=100"^@"C"+"273.15"="373.15 K"="373 K"` (rounded to a whole number)**

**The answer should also be rounded to `"400 K"` because `"100"^@"C"` has only one significant figure.
