Question

The boiling point of pure water is ______ ${}^{o}C$, at normal atmospheric pressure.

Answer 1

Boiling point of pure water:

1. A liquid changes into gaseous state at a constant temperature its called the boiling point.
2. Water is converted to vapors (gaseous state) at ${100}^{o}C$.
3. Thus, ${100}^{o}C$ is the boiling point of pure water.

Hence, The boiling point of pure water is 100 ${}^{o}C$, at normal atmospheric pressure.
