States of Matter (Phases of Matter): Solids, Liquids, and Gases

What is the scientific definition of matter?

• Anything that can be seen and touched

• Anything that takes up space and has mass

• Anything that is solid, liquid, or gas

• Anything that has weight and can be measured

What are the three primary phases of matter?

• Solid, liquid, and plasma

• Liquid, gas, and vapor

• Solid, liquid, and gas

• Plasma, solid, and liquid

Which of the following best describes the shape and volume of a solid?

• Indefinite shape, definite volume

• Indefinite shape, indefinite volume

• Definite shape, indefinite volume

• Definite shape, definite volume

How do the particles in a solid behave?

• They move freely and randomly throughout the volume.

• They are closely packed and vibrate in fixed positions.

• They are spread far apart and move rapidly.

• They slide past each other, taking the shape of their container.

What happens when a liquid in a sealed syringe is subjected to pressure?

• The liquid's volume decreases significantly.

• The liquid changes into a gas.

• The plunger will not move down.

• The liquid becomes a solid.

How do particles in a liquid behave differently from particles in a solid?

• Liquid particles are much farther apart than solid particles.

• Liquid particles vibrate in place, while solid particles move freely.

• Liquid particles can 'swim' past each other, unlike solid particles which are stuck in place.

• Liquid particles are completely stationary, while solid particles constantly move.

Which of the following properties confirms that gases are considered matter?

• Gases are often invisible.

• Gases have an indefinite shape.

• Gases take up space and have mass.

• Gases can expand or contract to fill a container.

What characteristic of gas particles allows gases to be easily compressible?

• Gas particles are constantly moving at rapid speeds.

• There is a lot of empty space between gas particles.

• Gases have an indefinite volume.

• Gas particles are very small.
