Answer 0

Solute

Question 1

The substance that does the dissolving.

Answer 1

Solvent

Question 2

What can be done to speed up the amount of time it takes to dissolve a solute?

Answer 2

A) increase the temperature (if the solute is a solid)

B) stir the solution

Question 3

Why does stirring speed up the time it takes for a solid to dissolve in a liquid?

Why does increasing the temperature do the same?

Answer 3

In both cases, it makes the molecules move around faster to make them bump (collide) with one another.

Question 4

Gases dissolve easier into liquids at (high or low) temps?

Answer 4

Low temps.

Question 5

Why would a gas come out of solution at a higher temp? (Think about heating a can of soda.)

Answer 5

The liquid and gas molecules would move faster, causing the gas bubbles to escape from the liquid.

Question 6

The word that means unable to dissolve.

Answer 6

Insoluble

Question 7

solubility

Answer 7

The ability to dissolve, can be affected by temperature, pressure, and amount of solvent.
