Answer:
Dear, your answer is
solubility is affected by current concentration, mechanical disturbance, temperature and pressure. So the answers are:
- Increasing temperature decreases the solubility of gases.
- Stirring increases the solubility of solids.
- Increasing pressure increases the solubility of gases.
- Decreasing the amount of solvent decreases the solubility of solids, liquids, and gases.

Answer:
A. True
Explanation:
Mole is the unit associated with measuring substances in chemistry. Chemicals are usually measured in moles and it is derived from the formula - mass/molar mass.
This makes the mole a definition of the representation of a macroscopic quantity of matter that can be used in the laboratory and hereby validates the answer as being true .
