Part 9: Which is NOT one of the 2 factors that increase the solubility of a GAS solute in liquid solvent:

increase temperature

increase pressure

decrease temperature

Part 9: Which is NOT one of the 3 factors that increase the solubility of a SOLID solute in liquid solvent:

increase pressure

increase temperature

increase agitation (stirring, shaking, mixing, etc)

incease surface area (i.e. crushing)

Part 9: 15 g of sugar cubes are dissolved in 120g of water at 20 C. What could be done to increase the rate of dissolution?

Stir the mixture

Use larger sugar cubes

Cool down the water

Add an electrolyte to the water

Part 9: Salt will dissolve in water more quickly if you stir it because...

Stirring increases the number of collisions

Stirring increases the kinetic energy

Stirring increases the surface area of solute

Stirring makes the particles move slower

Part 9: The solublity of a gas in a liquid occurs faster if the liquid is...

Cooled

Heated

Stirred

Agitated
