Aperson opens a 2-liter bottle of cola at a picnic. if the cap is left off the bottle, the cola will become 'flat' or lose it's carbonation. which statement below best summarizes why the cap must be kept tightly in place if the cola is to remain fresh? a) the cap prevents the liquid in the cola from evaporating. b) the cap keeps the atmospheric gases and liquid from mixing in the bottle. c) the cap keeps warm air from entering the two-liter bottle and raising the temperature of the cola solution. d) the cap keeps the pressure of the gas in the bottle at a high level preventing carbon dioxide from leaving the solution.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

About 3% of the water on earth is freshest. only about 40% of that freshwater is available for human use. why is so much freshwater unavailable for human use?
