States of Matter Lesson 1

How do particles behave in a solid?

• they are tightly packed together, but vibrate in place

• they are close together but can move around each other

• they are spread apart to fill the volume of their container

How do particles behave in a liquid?

• they are tightly packed together, but vibrate in place

• they are close together but can move around each other

• they are spread apart to fill the volume of their container

How do particles behave in a gas?

• they are tightly packed together, but vibrate in place

• they are close together but can move around each other

• they are spread apart to fill the volume of their container
