Question

The boiling point of water on the Kelvin scale is:

• A. $373.15K$
• B. $273.15K$
• C. $373K$
• D. $374.15K$

Answer 1

Answer: (A)

$373.15K$

The boiling point of a substance is the temperature at which the liquid changes into a vapor.

Boiling point of water is ${100}^{0}C$

To convert kelvin scale, we have to add 273.15 to ${}^{0}C$ scale value

So,

${100}^{0}C=100+273.15=373.15K$

Hence, option $A$ is correct.
