The three states of matter are a) solids b)liquids c)gases.

Answer 2

Matter is anything that has mass and occupies space. Matter can exist in three forms or phases: solids, liquids, or gases

The 3 states of matter are as :

1. SOLID
2. LIQUID
3. GAS

<> SOLID
____________________________________________________________

In a solid, the atoms are very attracted to one another. Because of this strong attraction, the atoms are held tightly together. The attractions are strong enough that the atoms can only vibrate where they are. They cannot move past one another. This is why a solid keeps its shape


<> LIQUID
_____________________________________________________________

In a liquid, the molecules are also in motion. The attractions between the molecules in liquids are strong enough to keep the molecules close to each other but not in fixed positions. Although the molecules stay very near one another, the attractions allow the molecules of a liquid to move past one another. This is why a liquid can easily change its shape. 

<> GAS
_____________________________________________________________

In a gas, the molecules are also moving. The attractions between the molecules of a gas are too weak to bring the molecules together. This is why gas molecules barely interact with one another and are very far apart compared to the molecules of liquids and solids. A gas will spread out evenly to fill any container.
