States of Matter

What are the three main states of matter?

• liquid, gas, plasma

• solid, liquid, gas

• solid, liquid, plasma

• solid, plasma, gas

Can you give an example of a solid?

• Water

• Sand

• Air

• Ice

What are the properties of solids?

• Definite shape, definite volume, high density, low compressibility

• Indefinite shape, indefinite volume, low density, high compressibility

• Definite shape, indefinite volume, low density, high compressibility

• Indefinite shape, definite volume, low density, high compressibility

How do particles behave in a liquid?

• Particles in a liquid behave by forming a rigid structure.

• Particles in a liquid behave by repelling each other.

• Particles in a liquid behave by vibrating in place.

• Particles in a liquid behave by moving freely and flowing past each other.

What is the main difference between gases and liquids?

• Gases have no fixed shape or volume, while liquids have a fixed volume but no fixed shape.

• Gases are always transparent, while liquids are opaque.

• Liquids are always colder than gases.

• Liquids have no mass, while gases have mass.

Explain what happens during the process of evaporation.

• Evaporation is the process by which a liquid turns into a gas or vapor when heated.

• Evaporation is the process by which a solid turns into a gas.

• Evaporation occurs only at extremely low temperatures.

• Evaporation is the process of a gas turning into a liquid.

Give an example of a phase change from solid to liquid.

• Sublimation of dry ice

• Condensation of steam

• Freezing of water

• Melting of ice

Describe the behavior of a gas.

• A gas behaves by having a fixed shape but no volume, and its particles move in a zigzag pattern.

• A gas behaves by being solid in form and structure, with particles tightly packed together.

• A gas behaves by having no definite shape or volume, and its particles move freely and quickly in all directions.

• A gas behaves by having a definite shape and volume, and its particles move slowly in one direction.

How does condensation occur?

• Condensation occurs when a solid is heated up.

• Condensation occurs when a gas is cooled down.

• Condensation occurs when a liquid is pressurized.

• Condensation occurs when a gas is exposed to light.

Explain how ice melting is an example of a phase change.

• Ice melting is an example of a phase change because it transitions from a solid phase to a gas phase.

• Ice melting is an example of a phase change because it transitions from a solid phase to a liquid phase.

• Ice melting is an example of a phase change because it transitions from a gas phase to a liquid phase.

• Ice melting is an example of a phase change because it transitions from a liquid phase to a solid phase.
