6th Science Lesson 2-1 States of Matter Review

Front

What causes solids to have a definite shape and definite volume?

Back

The particles that make up a solid are packed very closely together.

Front

What are crystalline solids?

Back

Solids that are made up of crystals.

Back

Sugar, salt, and snow are examples of crystalline solids.

Front

What are amorphous solids?

Back

Amorphous solids have particles that are not arranged in a regular pattern and do not melt at a distinct temperature.

Front

What is an example of an amorphous solid?

Back

Some examples of amorphous solids are glass, rubber, and plastics.

Front

How are the particles in a liquid arranged?

Back

The particles in a liquid are not fixed in place and can move around one another.

Front

Is honey more or less viscous than cranberry juice?

Back

Honey is more viscous than cranberry juice.

Front

Why can liquids flow from one place to another?

Back

Free moving particles allow a liquid to flow from place to place.

Front

Why can a glass of water be filled to the rim without spilling over?

Back

Surface tension allows a glass of water to be filled slightly above the rim without spilling over because the water molecules attract one another strongly.

Front

How are the particles in a gas arranged?

Back

The particles in a gas are widely spaced and collide with one another as they move around.
