Question

What is the physical state of water at 100°C?

Answer 1

The physical state of water:

Based on the physical nature of matter, matter exists in three states i.e., solid, liquid and gas. In the same manner, water can also exist in a solid-state (ice), liquid state (liquid water) and gaseous state (water vapour).

1. Water exists in different states at different temperatures.
2. It exists in the solid-state (ice) at or below $0°\mathrm{C}$.
3. It exists in the liquid state (liquid water) in the temperature range of $0°\mathrm{C}-100°\mathrm{C}$.
4. It exists in the gaseous state (water vapour) at the temperature above $100°\mathrm{C}$.
5. Therefore, the physical state of matter at $100°\mathrm{C}$ is in both liquid (water) and gaseous (water vapour) states.
