Question
Describe the Celsius scale of temperature.
✓
Answer
In Celsius scale, melting point of ice and boiling point of water are referred as "lower fixed point" and "upper fixed point" respectively. The temperature difference between the reference points is divided into $100$ divisions and each division is called "one degree Celsius" $\left(1^{\circ} C \right)$. Thus, the melting point of ice is taken as $0^{\circ} C$ and the boiling point as $100^{\circ} C$.
