What Is The Physical State Of Water At

(a) 25°C

(b) 0°C

(c) 100°C?

What is Matter?

The matter is anything that has mass and occupies space. The three basic states of matter are solid, liquid and Gas. Water We know that water exists in all three states of matter. Water exists as ice in solid form,  as water in liquid form, and as vapour in gaseous form. These interconversions of states of matter are visible to a common man in his day-to-day life.

So let us see at what suitable temperature the water exists in all these three forms:

(a) 25 º C  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 which 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.


If you keep an ice cube tray filled with water and freeze it for a few hours, you may observe the cubes where you poured water have become solid. Ice is the solid state of water.

(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.


When you boil water at your home after some time you observe the vapours coming out of the vessel. These vapours are the gaseous state of water.
