2021 Physical Science Final Review

How does temperature affect solubility for solids and liquids?

• a rise in temperature always increases solubility

• a rise in temperature always decreases solubility

• temperature does not affect solubility in a consistent way

What is one way to increase the solubility of sugar in water?

• increase water temp

• decrease water temp

• decrease the amount of water

• increase the amount of sugar

A substance whose shape can easily change is a

• solid

• metal

• fluid

• powder

The change from liquid to solid, or the reverse of melting is called

• condensation

• sublimation

• boiling

• freezing

Looking at each of these representations of states of matter, state the correct identification

• A- solid, B- Liquid, C- gas

• A- liquid, B - solid, C- gas

• A-gas, B-solid, C-liquid

• A-liquid, B- gas, C- solid

Water is referred to as the universal solvent because

• it is found throughout the universe

• many different substances dissolve in water

• all known substances react with water

• it covers almost half of the Earth's surface

Which would NOT increase the rate at which you dissolve powdered drink mix into a pitcher of water?

• heating the mixture

• stirring the mixture

• breaking up big pieces of the powdered mix

• adding more powdered drink mix

If you touch a cup and it feels hot, which best describes the heat transfer?

• Heat is traveling from you to the cup

• Heat is traveling from the cup to you

Sea breezes are formed because of this type of heat transfer that involves circulation of air:

• conduction

• convection

• radiation

Particles that are heated up move faster and faster because they gain

• radiation

• conduction

• kinetic energy

• convection
