Question

Convert $27°\mathrm{C}$ to Kelvin scale.

Answer 1

Step 1: Relation between Kelvin & Celsius scale
If $C$ is the temperature in Celsius scale, it can be converted into Kelvin scale $K$, by adding $273.15$.
i.e; ${}^{\circ }\mathrm{C}+273.15=\mathrm{K}$

Step 2: Conversion
It is given that temperature $=27{}^{\circ }C$
In Kelvin scale :
$27+273.15=K$

$\mathrm{K}=300.15$
Therefore in Kelvin scale $27{}^{\circ }C=300.15K$
