States of Matter

What happens to gas when you cool it down?

• The gas becomes solid.

• The gas becomes liquid.

• The gas expands.

• The gas increases in pressure.

Explain the particle arrangement in gases.

• Particles in gases are tightly packed and vibrate in place.

• Particles in gases are far apart and move freely, filling the entire volume of their container.

• Particles in gases are arranged in a fixed structure and do not move.

• Particles in gases are loosely arranged and can only move in one direction.

What happens to liquid when you cool it down?

• The liquid becomes solid.

• The liquid evaporates.

• The liquid becomes a gas.

• The liquid remains unchanged.

Explain the particle arrangement in liquids.

• Particles in liquids are far apart and do not move.

• Particles in liquids are close together but can move past each other, allowing liquids to flow.

• Particles in liquids are arranged in a fixed structure and cannot flow.

• Particles in liquids are loosely packed and vibrate in place.

What happens to liquid when you heat it up?

• The liquid turns into gas.

• The liquid freezes into solid.

• The liquid remains unchanged.

• The liquid evaporates into solid.

Explain the particle arrangement in solids.

• Particles in solids are loosely arranged and can move freely.

• Particles in solids are tightly packed in a fixed arrangement, allowing them to vibrate in place.

• Particles in solids are arranged in a random manner, leading to fluidity.

• Particles in solids are spread out and have large spaces between them.

What is melting?

• The process of a solid turning into a liquid when heated.

• The process of a liquid turning into a gas when heated.

• The process of a solid becoming a gas without turning into a liquid.

• The process of a liquid turning into a solid when cooled.

What is freezing?

• The process of a liquid turning into a solid when cooled.

• The process of a solid turning into a liquid when heated.

• The process of a gas turning into a liquid when cooled.

• The process of a liquid evaporating into a gas when heated.

Define solid.

• A state of matter characterized by fixed shape and volume, where particles are closely packed together.

• A state of matter that has no fixed shape but has a definite volume.

• A state of matter that can flow and take the shape of its container.

• A state of matter that exists only at extremely high temperatures.

Define gas.

• A state of matter that has no definite shape or volume, with particles that are far apart and move freely.

• A state of matter that has a definite shape but no definite volume.

• A state of matter that has a definite volume but no definite shape.

• A state of matter that is solid and has tightly packed particles.
