The document discusses the different phases of matter - solid, liquid, gas, plasma, and Bose-Einstein condensate. Solids have a definite shape and volume, with particles tightly packed and unable to move freely. Liquids have no definite shape but a definite volume, with particles able to change position and slide past one another. Gases have no definite shape or volume, with particles in constant motion throughout their container. Plasma exists at very high temperatures and pressures and is rare, while Bose-Einstein condensates form at very low temperatures near absolute zero from cooled particles.

2. Solids The solid phase of matter has a definite shape and volume. The particles in a solid are tightly packed together and cannot change position easily, they only vibrate.

4. Liquid The liquid phase of matter has no definite shape but it has a definite volume. Liquids have no definite shape because the particles in a liquid are able to change position and slide past one another.

5. Examples of Liquids Water Dish soap Bubble solution Laundry detergent Mercury

6. Gas The gas phase of matter has no definite shape or volume. The particles in a gas are always in motion and they can move freely to all parts of a container.

7. Examples of Gases Air Oxygen Neon Radon

8. Plasma The plasma phase of matter is similar to the gas phase but exists in only very high temperatures and pressures and is very rare.

9. Examples of Plasma Auroras Lightning Stars

10. Bose-Einstein Condensate Phase A Bose-Einstein condensate is a gaseous super-fluid phase formed by particles cooled to very low temperatures very near to absolute zero.
