1. SOLID, LIQUID AND GAS SCIENCE 5

2. A property of matter A property of matter describes how an object looks, feels, smells, reacts It differentiated solid , liquid, and gas from one another. Knowing their properties is the best way to identify and distinguish the states of matter.

3. SOLID Solid materials have particles (atoms or molecules) that are tightly connected with one another. Since these particles are very attracted to one another, they vibrate but do not move. This is how solid objects retain their shape unless something is done to deliberately change them. Solid materials also have a definite volume.

5. LIQUID The attraction of molecules in liquids is weaker compared to that in solids. The particles vibrate, move more freely, and slide past one another. Because of this, liquid materials do not have their own shape. They only take the shape of their container.

6. GAS The particles of gases are dispersed randomly. These particles have the weakest attraction to one another as compared to the attraction between particles of the other states of matter. The molecules of gases move constantly in an unsystematic way. Hence, it is hard to identify their shape. Gases can fill up an entire container.
