If you knock over a capped bottle of soda, the bottle becomes
very pressurized. If you place the beverage in a refrigerator, the
pressure decreases. What phenomena explain this change? (select all
that apply)
Refrigerator has lower temperature than out side. Since volume
of vapor is directly proportional to temperature (VT,
Charle's law), volume of vapor contracts with decrease in
temperature inside refrigerator.
Hence 1st option is correct.
CO2 condenses at melting point temperature of - 55.6 oC. But such a low temperature is not achieved by a refrigerator. Hence CO2 cannot condense to form a liquid phase.
Hence 2nd option is wrong.
Solubility of gases is inversely proportional to temperature. Hence solubility of CO2 is higher at lower temperature inside refrigerator.
Hence 3rd option is correct.
Keeping the bottle in refrigerator gives sufficient to establish equilibrium and shifts the equilibrium towards the more dissolved gas.
Hence 4th option is correct.
The volume of water contracts till the temperature decreases to 4 oC. But after 4 oC, the volume of water expands till the freezing point of 0 oC.
Hence 5th option is correct till the temperature inside the refrigerator is 4 oC.

You open a soda bottle and allow all the CO2 to "fizz" out of the soda. The soda is now flat, and contains little to no CO2. Which of the following techniques might be useful for recarbonating your soda back to its original levels of carbonation? Heat the soda and then shake Place the soda back in your refrigerator and allow it to cool back down. Place the soda in a sealed container that contains a high pressure of carbon...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
