Question

What is the temperature in Kelvin scale, at which water starts boiling?

• A. 0 K
• B. 100 K
• C. 273 K
• D. 373 K

Answer 1

The correct option is D 373 K

Kelvin is another unit of temperature. The relation between Celcius and Kelvin scale is as follows
$0^{\circ }C=273K$
To convert a temperature in Celcius scale to Kelvin scale we have to add 273 to the given temperature.
The boiling point of water is ${100}^{\circ }C$.
On Kelvin scale, ${100}^{\circ }C=273+100=373K$
