A free Chemistry lesson for Class 3 children.
Everything around us is a solid, a liquid or a gas.
A solid has a shape of its own. A stone and a book are solids.
A liquid flows. It takes the shape of the pot we keep it in.
Water, milk and oil are liquids.
A gas spreads out and fills all the space it gets.
The air around us is a gas. We cannot see it, but we can feel it.
In a solid, the tiny particles are packed very close together.
In a gas, the particles are far apart and move about freely.
