Exploring States of Matter

What are the three states of matter?

• solid, liquid, gas

• rock, water, steam

• ice, mist, smoke

• plasma, vapor, foam

Describe the properties of solids.

• Solids have no definite shape or volume.

• Solids have a definite shape and volume, are incompressible, have high density.

• Solids are easily compressible and have low density.

• Solids can only be crystalline and not amorphous.

How do liquids differ from solids?

• Liquids have a fixed shape and volume like solids.

• Solids can flow and change shape like liquids.

• Liquids differ from solids in that they have no fixed shape and can flow, while solids maintain a fixed shape and volume.

• Liquids are always denser than solids.

What is the property of gases that allows them to fill a container?

• Gases remain in a fixed shape regardless of the container.

• Gases can only occupy a small part of a container.

• Gases are denser than liquids and do not expand.

• Gases expand to fill the entire volume of their container.

What happens to the particles in a solid when it is heated?

• The particles vibrate more and move apart as they gain energy.

• The particles freeze and become immobile.

• The particles expand and form a liquid immediately.

• The particles lose all energy and collapse into a solid mass.

Define melting in terms of state changes.

• Melting is the transition of a substance from solid to liquid state due to the absorption of heat.

• Melting is the change of a substance from liquid to solid state.

• Melting occurs when a gas turns into a solid.

• Melting is the process of a liquid becoming a gas.

What is condensation?

• Condensation is the process of water vapor turning into liquid water.

• Condensation is the freezing of water into ice.

• Condensation is the evaporation of water from a surface.

• Condensation is the process of liquid water turning into water vapor.

How does evaporation occur?

• Evaporation occurs when vapor condenses into liquid.

• Evaporation is the process where liquid turns into vapor due to the escape of molecules from the surface at any temperature.

• Evaporation is the process of freezing a liquid into a solid.

• Evaporation happens when a solid turns into a gas without becoming liquid.

What is the process called when a gas turns into a liquid?

• Condensation

• Precipitation

• Sublimation

• Evaporation

Explain what happens during freezing.

• Freezing is the process where a liquid turns into a solid as its temperature decreases.

• Freezing is when a solid turns into a gas as it heats up.

• Freezing is the process of melting ice into water.

• Freezing occurs when a liquid evaporates into the air.
