Atomic Theory

Front

The kinetic theory of matter states that matter is made up of tiny particles that are in constant motion. Which of the following relates to the kinetic theory?

• the relationship between mass and weight
• the relationship between a balance and a scale
• the relationship between solids, liquids, and gases
• the relationship between mass, volume, and density

Back

the relationship between solids, liquids, and gases

What can Susie say about the motion of the particles in a cup of hot water and the water vapor above the cup?

Back

They are always moving

Front

How should Ben's second model differ from the first when showing how water and iron particles move as the pot of water is heated?

Back

The water particles should slide past each other faster, and the iron particles should vibrate.

Front

In which state of matter are the particles able to move around one another? Options: gases only, liquids only, gases and liquids only, gases, liquids, and solids

Back

gases and liquids only

Front

Which claim about the carbon atoms that make up a diamond can be supported by evidence? Options: They can slip past one another slowly. They are always vibrating in place. They vibrate only when they are heated. They are locked in place and do not move at all.

Back

They are always vibrating in place.
