Water at 25°C is present in the liquid state.
The water which we use for our day-to-day activities is in a liquid state.
The water we use for drinking, cooking, washing, etc., all are in a liquid state.
b) 0ºC
At 0°C, water exists in solid-state.
We know that the freezing point of water is 0 °C.
The liquid form of water starts to become solid (ice) at this temperature
(c) At 100ºC
At 100°C, water exists in a gaseous state.
We know that the boiling point of water is 100°C.
The water starts to evaporate after attaining this high temperature.
Example: When you boil water in your home, you observe the vapours coming out of the vessel after some time. These vapours are the gaseous state of water.
