Question

write a short note on change of state of water​

Answer 1

Answer:

We can change a solid into a liquid or gas by changing its temperature. This is known as changing its state. Water is a liquid at room temperature, but becomes a solid (called ice) if it is cooled down. The same water turns into a gas (called water vapor) if it is heated up...

Answer 2

Answer:

Matters can be changed from one state to another state. A solid can be changed into liquid and a liquid can be changed into gas. Most of the metals, which are solid, turn into liquid on heating and turn into vapor on further heating.

The change of state of matters depends upon mainly two factors:

Temperature

Pressure

Solids change into liquid with increase in temperature. (Solid → Liquid)

A liquid changes into gas by increase in temperature. (Liquid → Gas)

Gas changes into liquid by decrease in temperature. (Gas → Liquid)

liquid changes into solid by decrease in temperature. (Liquid → Solid)
