States of Matter

Define liquid.

• A state of matter that has a definite volume but takes the shape of its container, with particles that are close but can move past each other.

• A state of matter that has a definite shape and volume, with particles that are tightly packed.

• 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 volume but no definite shape, with particles that are loosely packed.

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.

What is evaporation?

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

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

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

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

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 sublimation?

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

• The process of a gas turning into a liquid.

• The process of a liquid turning into a solid.

• The process of a solid turning into a liquid.

Define gas.

• A state of matter that has a definite shape and volume.

• 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 is always solid and rigid.

• A state of matter that can be easily compressed and has a fixed volume.

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 cool it down?

• The liquid evaporates.

• The liquid becomes solid.

• The liquid remains unchanged.

• The liquid turns into gas.

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 slightly compressed and can slide past each other.

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.
