SOLIDA solid is matter that has that has definite size and shape.
Example: Put a sneaker in a box. It stays the same.

LIQUIDA liquid takes the shape of any container.
Example: Pour juice into a glass. The juice will take on the shape of the glass.

GasGas is matter that has no definite shape. Gases take the shape of
whatever container they are in .
Example: The air all around us is a gas.

Which do you think would have the greater volume? The greater mass?
Why?1 kg of feathers
1 kg of rocks

Density is defined as mass per unit volume. It is a measure of how tightly packed and how heavy the molecules are in an object. Density is the amount of matter within a certain volume.
