I need some help with a soda experiment in science?!
1) When does more gas stay dissolved, at a higher temperature or a lower temperature?
2) What happens to the solubility of oxygen gas as the temperature is raised?
3) Does a cooler or warmer lake have more oxygen dissolved in its water?
Answers: Below are a few questions that I need help with. Please feel free to answer as many or as few as you can. The best answer is always rewarded!
1) When does more gas stay dissolved, at a higher temperature or a lower temperature?
2) What happens to the solubility of oxygen gas as the temperature is raised?
3) Does a cooler or warmer lake have more oxygen dissolved in its water?
You can read about the temperature effects on Henry's Law in the Wikipedia. It should make answering these questions easy.
Think of opening a warm soda pop vs. opening a chilled soda pop. Under which condition does the CO2 escape faster upon first opening?
use the formula PV=nRT
read this for an explanation of gas laws, what happens to gas solubility when temperature goes up
