Understanding States of Matter

What are the basic building blocks of matter?

• Atoms and molecules

• Protons and neutrons

• Electrons and ions

• Energy and mass

Which of the following is a characteristic of solids?

• Indefinite shape

• Definite volume

• High kinetic energy

• Low density

How do particles in a liquid behave compared to those in a solid?

• They are tightly packed and vibrate in place

• They are loosely packed and flow around each other

• They are stationary and do not move

• They are spread out and move freely

What happens to gas particles when they are confined in a container?

• They contract and occupy less space

• They expand to fill the container

• They form a solid

• They remain stationary

Which state of matter has particles with the highest kinetic energy?

• Liquid

• Solid

• Gas

• Plasma

What is the process called when a solid turns directly into a gas?

• Melting

• Sublimation

• Vaporization

• Condensation

What is the term for the change of a liquid to a gas?

• Condensation

• Freezing

• Sublimation

• Vaporization

What happens to the particles of a substance when heat is removed?

• They become charged

• They slow down and move closer together

• They move faster and spread apart

• They remain unchanged

Which of the following is an example of a non-Newtonian fluid?

• Oil

• Water

• Mercury

• Oobleck

What is the effect of temperature on the rate of chemical reactions?

• Temperature has no effect on reactions

• Higher temperatures speed up reactions

• Lower temperatures speed up reactions

• Higher temperatures slow down reactions
