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)

Partial Question 2 3.33/5 pts 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) The volume of the vapor contracts. Some carbon dioxide condenses to form a liquid phase. The temperature and pressure in your refrigerator is not adequate to induce a phase change. The solubility of carbon dioxide is higher at the lower temperature. Adequate time has been provided to allow the equilibrium system to shift towards more dissolved gas based on the pCO2 The volume of the liquid contracts.

Answer 1

Refrigerator has lower temperature than out side. Since volume of vapor is directly proportional to temperature (V $\alpha$ T, 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 ^o​​​​​​​C.

Hence 5th option is correct till the temperature inside the refrigerator is  4 ^o​​​​​​​C.
