States of Matter

What are the characteristics of a solid?

Definite shape and volume, with particles closely packed together.

How do liquids differ from solids?

Liquids have a definite volume but no definite shape, with particles that are close but can move past one another.

What is a defining characteristic of gases?

Gases have no definite shape or volume, and their particles are far apart and move freely.

What is Brownian Motion?

The erratic, random movement of particles suspended in a fluid, which is either a liquid or a gas.

Describe the arrangement of particles in a solid.

Particles are closely packed together.

What happens to particles in a liquid compared to those in a solid?

Particles in a liquid can move past one another, unlike in a solid where they are fixed in place.

What is the state of particle movement in gases?

Particles in gases move freely and are far apart.

What happens to the shape of a liquid when it is placed in a container?

A liquid takes on the shape of its container but maintains a definite volume.

In what states of matter is Brownian motion observed?

Brownian motion is observed in fluids, which can be either liquids or gases.

How do the properties of gases reflect their particle arrangement?

The properties of gases reflect a lack of definite shape and volume due to the free movement of particles that are far apart.
