Question

The boiling point of water is 100° C. Express this in SI units (Kelvin scale).

Answer 1

373 K

Explanation:

We have boiling point of water to be 100° C.

• Now we are asked to find the temperature in SI units.
• The relation between the scales is given by the following relation,

$\frac{C}{100}=\frac{K-273}{100}$

• So using this scale we can convert the desired celsius temperature into kelvin scale.
• So from the data the boiling point is taken as the temperature in celsius scale.

$\frac{100}{100}=\frac{K-273}{100}$

$K=373$

Hence the temperature on the kelvin scale is 373 .

Answer 2

In Kelvin it Becomes 373 K

Explanation:

°C = K - 273.15

• It's a simple one-step process of conversion of Celsius to Kelvin.

• In order to convert Celsius to kelvin, just add 273.15 to the given celsius temperature and vice versa for Kelvin to Celsius.

Your answer will be in Kelvin.

• While there is no degree symbol for Kelvin, you need to add the symbol to report a Celsius temperature.

Here,  

• 100°C can be converted to Kelvin by adding 273

So, 100 + 273 = 373 Kelvin or 373 K
