# Explain what solids, liquids, and gases are. Part 1

EXPLAIN WHAT SOLIDS, LIQUIDS, AND GASES ARE.

Contributed by: Sarah Cate N.

This was the question that was given to me. I have studied it before, but I did not know a lot about them until now. Solids, liquids and gases are 3 out of the 5 states of matter (Plasma and Bose Einstein Condensate being the others.)

Solids are when molecules are close and dense so fingers most likely could not go through. (But sometimes could.) An example of a solid is ice wood or metal. A liquid is when molecules are not as close and they from a shapeless liquid that you could shape, but it would most likely not stay in that shape if there was nothing to hold it up. You could put your finger through a liquid. (But sometimes that liquid is not safe for skin, such as an acid.) An example of a liquid is water milk or apple juice. Gases are when molecules are very far apart and they bounce around. A finger could definitely go through gases. An example of a gas is carbon dioxide, oxygen, or steam.

A solid is when matter has little energy, A liquid has more but not much energy, and a gas has lots more energy.

Figure 1 this is a picture that I drew that has examples of the 5 states of matter.

RELATED TOPIC 1

Plasma is the fourth state of mater. It has much more energy than the other 3. Plasma is found mostly in space but it is also lightning. Other examples of plasma are stars, and the sun. (Which is a star but to bad.)

RELATED TOPIC 2

Bose Einstein condensate (also known as a super Adam) is the 5 state of mater. It was only discovered in 1995, only 16 years ago. There are no examples of Bose Einstein Condensate (BEC) because it is what it is, BEC is BEC.

Figure 2: This is a picture of BEC

GLOSSARY:

BEC: Bose Einstein Condensate. It is named after Albert Einstein and Satyendra Nath Bose. If you cool something own enough all the molecules would combine into one, and you can’t see it any more. But when you heat it back up, all the molecules come back, but they don’t remember where they are.

Plasma: 4 state of matter, has a lot of energy. Ex: sun, stars, lightning.

Molecules: Makes up an Adam.
