Opening champagne. In a bottle of champagne, the pocket of gas (primarily carbon dioxide) between the liquid and the cork is at pressure of p = 5.07 atm. When the cork is pulled from the bottle, the gas undergoes an adiabatic expansion until its pressure matches the ambient air pressure of 1.00 atm. Assume that the ratio of the molar specific heats is γ = 4/3. If the gas has initial temperature T = 4.7°C, what is its temperature at...
There is a compound Z that exists in the liquid phase at room temperature and pressure with a vapor pressure of 0.2 atm. When 250 ml of Z is mixed with 250 ml of water the resulting mixture has a lower vapor pressure than predicted. Explain what this means in terms of the intermolecular forces of the solute(Z) and the solvent ( water). Is Z likely to participate in hydrogen bonding? Why or why not. When pure compound Z (as...
