Question

If the boiling point of water in Kelvin scale is 373 K. What is the boiling point of water on degree celcilus scale(${}^o$C)?

• A. 473${}^o$C
• B. 173${}^o$C
• C. 100${}^o$C
• D. 73${}^o$C

Answer 1

The correct option is C 100${}^o$C

The temperature at which a liquid starts boiling is known as its boiling point.

The relation between Celsius (${}^o$C) and Kelvin (K) scale is as follows-
${}^{\circ }C=Kelvin-273$

The boiling point of water in Kelvin scale is 373 K.
So, the boiling point of water on ${}^o$C scale would be-
$373-273={100}^o$C
