How can you describe the motion of particles in a solid?How can you describe the motion of particles in a liquid?How can you describe the motion of particles in a gas?

A solid has a definite shape and a definite volume.

What are some examples?

The particles in a solid are closely locked in position and can only vibrate, as they do not have enough energy to slide past one another.

There are 2 types of solids:

1)Crystalline Solids

2)Amorphous Solids

Particles form a regular repeating pattern.

These patterns create crystals.

Examples: Salt, Sugar, Snow, Quartz

Melts at a specific temperature

Particles are not arranged in a regular pattern.

Examples: Plastic, Rubber, Glass, Butter

Does not melt at a distinct temperature, may become softer or change into other substances.

A liquid has a definite volume but not a definite shape. It takes on the shape of its container.

What are some Examples?

In general, particles in a liquid are packed almost as closely as a solid, but the particles move freely.

Compared to particles in a solid, the particles in a liquid are more loosely connected and can collide with and move past one another.

This is why a liquid flows and has no definite shape.

Surface Tension:- Result of an inward

pull among the molecules of a liquid that brings the molecules on the surface closer together

- Causes water to bead up and insects to walk on water

Viscosity:- A liquid’s resistance

to flowing- Depends on size and

shape of particles and attraction between them

- High viscosity = slow flow, like honey

- Low viscosity = quick flow, like water

A gas does not have a definite shape or a definite volume. Gas particles can spread apart or be squeezed together depending on the container.

What are some examples?

In gases, the atoms and molecules are free to move independently, colliding frequently.

FLUIDS:

Fluid means a “substance that flows.”

Both liquids and gases are considered fluids.

What are the 3 States of Matter?

Which state of matter has a definite volume, but no shape of its own?

Solid, Liquid, Gas

Liquid

What state of matter is not considered a fluid?

Does juice have a high or low viscosity?

Solids

Low
