6th Science Lesson 2-1 States of Matter Review

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

• The particles that make up a solid are separated by air.
• The particles that make up a solid are packed very closely together.
• The particles that make up a solid are stacked in a vertical line.
• The particles that make up a solid are bouncing around past one another.

What are crystalline solids?

• Solids that are made up of rocks.
• Solids that are made up of erasers.
• Solids that are made up of crystals.
• Solids that are made up of sugar.

What are some examples of crystalline solids?

• Solids, liquids, and gases are examples of crystalline solids.
• Glass, rubber, and plastics are examples of crystalline solids.
• Sugar, salt, and snow are examples of crystalline solids.
• Diamonds, emeralds, and pearls are examples of crystalline solids.

What are amorphous solids?

• Amorphous solids have a definite shape but not a definite volume.
• Amorphous solids have particles that are not arranged in a regular pattern and do not melt at a distinct temperature.
• Amorphous solids have surface tension and viscosity.
• Amorphous solids have free moving particles that allow it to flow from place to place.

What is an example of an amorphous solid?

• Some examples of amorphous solids are glass, rubber, and plastics.
• Some examples of amorphous solids are solids, liquids, and gases.
• Some examples of amorphous solids are viscosity and surface tension.
• Some examples of amorphous solids are sugar, salt, and snow.

How are the particles in a liquid arranged?

• The particles in a liquid are fixed in place and vibrate in place.
• The particles in a liquid are not fixed in place and can move around one another.
• The particles in a liquid are free flowing and arranged in a crystal structure.
• The particles in a liquid cannot move around one another and melt at a constant temperature.

Is honey more or less viscous than cranberry juice?

• Honey is more viscous than cranberry juice.
• Honey is less viscous than cranberry juice.
• Honey has the same viscosity as cranberry juice.

Why can liquids flow from one place to another?

• The high viscosity allows a liquid to flow from place to place.
• The surface tension allows a liquid to flow from place to place.
• Melting at a distinct temperature allows a liquid to flow from place to place.
• Free moving particles allow a liquid to flow from place to place.

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

• Viscosity allows a glass of water to be filled slightly above the rim without spilling over because the water molecules attract one another strongly.
• Crystalline patterns allow a glass of water to be filled slightly above the rim without spilling over because the water molecules attract one another strongly.
• 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.
• Amorphous patterns allow a glass of water to be filled slightly above the rim without spilling over because the water molecules attract one another strongly.

How are the particles in a gas arranged?

• The particles in a gas are widely spaced and collide with one another as they move around.
• The particles are free moving and allow it to flow from place to place.
• The particles are closely locked in position such that they cannot move around one another on their own and only vibrate in place.
• The particles can be filled slightly above the rim without spilling over because the molecules attract one another strongly.
