What does the kinetic theory say about the motion of atoms?
Atoms are always in motion and the temperature affects their speed.
Atoms are stationary and do not move.
Atoms move only when observed.
Atoms move in a predictable pattern.
Which of the following lists contains seven examples of physical properties?
Color, odor, melting point, boiling point, density, solubility, hardness
Color, taste, reactivity, flammability, density, solubility, hardness
Color, odor, reactivity, flammability, density, solubility, hardness
Color, taste, melting point, boiling point, reactivity, solubility, hardness
The composition of a compound is described by its:
chemical formula
physical state
color
density
What happens to the temperature of a substance during a phase change?
The temperature increases.
The temperature decreases.
The temperature remains constant.
The temperature fluctuates.
Chemical properties can be observed under what conditions?
When a substance undergoes a chemical change
When a substance is heated
When a substance is cooled
When a substance is mixed with water
Predicting: What happens to the pressure in a tire if air is slowly leaking out of the tire?
The pressure increases.
The pressure decreases.
The pressure remains the same.
The pressure fluctuates.
A pat of butter melts and then burns in a hot frying pan. Which of these changes is physical and which is chemical?
Melting is physical, burning is chemical
Melting is chemical, burning is physical
Both are physical changes
Both are chemical changes
What three factors affect gas pressure?
Temperature, Volume, and Number of Molecules
Temperature, Mass, and Density
Volume, Density, and Mass
Number of Molecules, Mass, and Density
The energy of a system changes during a phase change by:
increasing as heat is absorbed or decreasing as heat is released
remaining constant
increasing only
decreasing only
A gas is able to fill a container of any size or shape because:
it has a definite shape and volume.
its particles are in constant random motion.
it is heavier than a solid or liquid.
it is lighter than a solid or liquid.
When you describe a liquid as thick, are you saying that it has a high or a low viscosity?
High viscosity
Low viscosity
The rusting of an iron bar decreases the strength of the bar because:
rust forms a protective layer on the iron bar.
rust increases the weight of the iron bar.
rust causes the iron to expand and weaken.
rust improves the appearance of the iron bar.

Melting, Freezing, Boiling, Evaporation, Condensation, Precipitation
Melting, Freezing, Vaporization, Condensation, Boiling, Evaporation
Melting, Freezing, Condensation, Precipitation, Sublimation, Deposition
Three uses of physical properties are:
Identifying substances, determining state changes, and measuring density
Cooking, cleaning, and painting
Driving, flying, and sailing
Reading, writing, and speaking
Two processes that are used to separate mixtures are:
Filtration and Evaporation
Melting and Freezing
Condensation and Sublimation
Oxidation and Reduction
A mixture can be separated by distillation because of differences in what property?
Boiling points
Color
Density

Compare the properties of a raw egg to those of a hard-boiled egg.
A raw egg has a liquid interior, while a hard-boiled egg has a solid interior.
A raw egg is heavier than a hard-boiled egg.
A raw egg is white, while a hard-boiled egg is brown.
A raw egg has a solid yolk, while a hard-boiled egg has a liquid yolk.
Sharpening a pencil is an example of a physical change because:
it changes the chemical composition of the pencil.
it changes the shape and size of the pencil without altering its chemical structure.
it creates a new substance.
it involves a chemical reaction.
The arrangement of atoms in most solids differs from the arrangement of atoms in a liquid in that:
atoms in solids are closely packed in a fixed structure, while in liquids they are more randomly arranged and can move past each other
atoms in solids are more randomly arranged and can move past each other, while in liquids they are closely packed in a fixed structure
atoms in both solids and liquids are closely packed in a fixed structure
atoms in both solids and liquids are more randomly arranged and can move past each other
Increasing the number of particles of a contained gas affects its pressure by:
Increasing the pressure
Decreasing the pressure
No change in pressure
Depends on the type of gas
