Three cups of carbonated soda (CO2 gas) are lowered into cups of water at varying temperatures. All other factors being equal, in which cup does the greatest release of dissolved gases occur?
(Release means it cannot be dissolved.)
Heat pollution happens when factories put hot water into local rivers.
How would hot water affect the oxygen levels in those rivers?
Oxygen gas would be released out of the river.
Oxygen gas would be absorbed/dissolved into the river.
Levels of oxygen gas would not change.
Oxygen gas would combust in the river.

Three bottles of baby formula are prepared at the same temperature.
Which one will best dissolve the formula?

Maria stirs the mixture once.
Kevin stirs the mixture twice.
Jose stirs the mixture three times.
Which type of sugar dissolves the fastest?
powdered sugar
granulated sugar
sugar cubes
Why are most drink mixes sold as powders?
Powders have large surface areas, so they dissolve faster.
Powders have a higher temperature, so they dissolve more.
Powders have a lower Ka value, so they're less acidic.
Powders have a larger molar mass, so they taste better.
Samantha is making a saturated solution of copper sulfate (s). What steps can she take to dissolve it faster?
crush the copper sulfate solute into small pieces
heat up the solution
stir the solution
cool down the solution
Diego is making a pitcher of grape Kool Aid. Which action will NOT help him dissolve it faster?
heat up the water
cool down the water
stir the pitcher quickly
use powdered sugar instead of granulated
