EPOM Lesson 11 Daily Grade

Front

Gases and solubility: What happens to the solubility of gases as temperature increases?

Back

Gases always decrease in solubility with increasing temperature.

Front

Heat and solubility: Does the behavior of solids depend on whether heat is given off or taken in when they dissolve?

Back

True

Front

Solubility and temperature: In what type of water do solutes dissolve quicker?

Back

Solutes dissolve quicker in warm water.

Front

Solubility of substances: Are different substances equally soluble in water?

Back

False

Front

Dissolution of sand: Can sand dissolve in water?

Back

No.

Front

Definition of solubility: What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent at a given temperature and pressure.

Front

Factors affecting solubility: Name two factors that affect the solubility of a substance.

Back

Temperature and pressure.

Front

Endothermic vs Exothermic dissolution: What is an endothermic process in dissolution?

Back

An endothermic process is when a substance absorbs heat from the surroundings while dissolving.

Front

Endothermic vs Exothermic dissolution: What is an exothermic process in dissolution?

Back

An exothermic process is when a substance releases heat into the surroundings while dissolving.

Front

Saturation point: What is a saturated solution?

Back

A saturated solution is one that contains the maximum amount of solute that can dissolve at a given temperature.
