Exploring Matter in Our Surroundings

What are the three main states of matter?

• solid, liquid, gas

• mist

• plasma

• vapor

Which state of matter has a definite shape and volume?

• Liquid

• Gas

• Plasma

• Solid

What property of solids allows them to maintain their shape?

• Strong intermolecular forces

• Weak intermolecular forces

• Low density

• High thermal conductivity

Which of the following is a characteristic of liquids?

• Definite volume and shape of the container.

• Fixed volume and shape regardless of the container.

• Definite shape and variable volume.

• No definite volume and shape of the container.

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

• The particles in a gas lose energy and move closer together when heated.

• The particles in a gas move faster and collide more frequently when heated.

• The particles in a gas become denser and settle at the bottom when heated.

• The particles in a gas slow down and collide less frequently when heated.

Which state of matter has particles that are closely packed together?

• Solid

• Gas

• Plasma

• Liquid

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

• Sublimation

• Freezing

• Melting

• Condensation

Which property of liquids allows them to flow?

• The property of liquids that allows them to flow is their ability to have loosely packed molecules that can move past each other.

• Liquids have tightly packed molecules that cannot move.

• Liquids have a fixed shape that prevents movement.

• Liquids are always at a constant temperature.

What is the term for the change of state from gas to liquid?

• Condensation

• Sublimation

• Freezing

• Evaporation

Which of the following is NOT a property of gases?

• Ability to flow and take the shape of their container

• Having a definite shape or volume

• Compressibility under pressure

• Low density compared to liquids
