Honors Chemistry Chapters 1-3 Exam Questions And
Answers 2024 Tests
What is the definition of chemistry? ANS The study of the properties and transformations of matter
What is the definition of matter? ANS Anything that has mass and occupies space-- things you can see, touch,
taste, or smell
What is the definition of a property? ANS A characteristic that can be used to describe a substance. Substances
have both physical and chemical properties
What is the definition of a transformation? ANS A change in the properties of matter with time. There are
physical chances and chemical changes
Substances have both BLANK and BLANK properties ANS Physical and chemical
Define physical properties ANS Observing this property DOES NOT ALTER the makeup of a substance.
EX: Density, color, and melting points.
Define chemical properties ANS Observing a chemical property DOES ALTER the substance.
EX: Chemical composition, what matter is made of, and chemical reactivity, how matter behaves.
Is a change in state a chemical or physical change? ANS Physical change
Is change in particle size a chemical or physical change? ANS Physical change
Is the formation of mixtures a chemical or physical change? ANS Physical change
Is the separation of a mixture a chemical or physical change? ANS Physical change
, If heat, light, or electrical energy is emitted or absorbed, is that a physical or chemical change? ANS Chemical
change
Is potassium reacting with water a chemical or physical change? ANS Chemical change
What are the three states of matter? ANS Solid, Liquid and Gas
What is the definition of a solid? ANS A substance that has a definite shape and volume. They are rigid and
dense
What is the definition of a liquid? ANS A substance that has a definite volume but that changes shape to fill the
container. They are dense and fluid
What is the definition of a gas? ANS A substance that has neither a definite volume nor a definite shape.
Gases are BLANK density fluids. ANS Low
What effects the state of matter? ANS Pressure and temperature
What is the definition of a pure substance? ANS Matter that is uniform in its chemical composition and
properties
What is an example of a pure substance? ANS Water
What is the definition of a mixture? ANS A blend of two or more pure substances in any ratio, each retaining
their identity?
What is an example of a mixture? ANS Dissolving sugar in water
What can separate mixtures into one or more pure substances? ANS Physical changes, such as evaporation and
condensation
What are the two types of pure substances? ANS Elements and Chemical Compounds
