Evaporation
What is Evaporation?
Evaporation is the process in which a liquid changes into a gas. It happens when the particles in a liquid gain enough energy to escape into the air.
How Does It Happen?
When a liquid is heated, its particles move faster. Some particles at the surface gain enough energy to leave the liquid and become a gas. This process is called evaporation.

Is there a substance that cannot change forms?
What is Plasma? what is the relevance of learning thé states of matter?
Why is it called ‘states of matter’ and not ’forms of matter’?
