Question

under what condition solid liquid and gaseous change their state ?​

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.

The process by which a substance changes from the solid phase to the

liquid phase is known as melting. The process by which a substance changes from the liquid phase to the solid phase is known as freezing. The process by which a substance changes from the liquid phase to the gaseous phase is known as evaporation.
