What is phases of matter?

Question

This is science question

Answer 1

Solid,liquid and gas.

Answer 2

A phase of matter is a state where its chameical and physical properties are relatively uniform, and are different from the same matter in another phase. At the temperature at which the matter moves from one phase to another, there will be discontinuous changes in some of its properties.

The most familiar examples are gas, liquid and solid. Some of the abrupt changes are obvious here - for instance, when a liquid boils its temperature does not change, but its volume increases 1 million fold.

There are lots of other less familiar phases such as liquid crystals, plasmas, superfluids etc.
