Matter can be defined as anything which has mass and occupies space. There are three states of matter namely Solid, Liquid and Gas.
- Solid: Solid consists of particles which are tightly bound together. They have fixed geometrical shape.
- Liquid: They are loosely bound particles and do not have any fixed shape but they take the shape of the container in which they are kept.
- Gas: Gases consists of very loosely bound particles and do not have any shape.
Some of the basic physical unit of matter or fundamental SI units are as follows:

Mixtures are of two types: Homogeneous and Heterogeneous.
- Homogeneous Mixtures: Homogeneous mixture can be defined as a mixture where the composition of the mixture is uniform throughout.
- Heterogeneous Mixtures: Heterogeneous types of mixture are those where all the elements don't mix.
