Which is more efficient for cooling a mass of cold water or a mass of cold air?

A mass of cold water.
This is because the molecules are closer together in water than air, so there's more molecules to take away the heat, in a manner of speaking.
Generally speaking, liquids have a higher heat transfer coefficient than gasses.
A:
The mass of cold water definitely. I actually just finished an experiment that tested that question the water was at least an hour faster.

If the volume is the same, water (having a larger density) would have a much larger mass, and therefore take much longer to cool down or heat up. Even for the same mass, water will take longer to cool down or heat up, because of its larger specific heat.

If a cold piece of metal is placed in an equal mass of warm water will the final temperature be closer to the original temperature of the metal or the water?
Temperature of the water
What is the mass of 120 ml of water?
The mass of 120 mL of water is 120 g.
What is the mass of 100 ml water?
The mass of 100 mL of water is 100 g.
Does dye travel faster through cold water or hot water?
Hot Water. Heat is the simple term for average kinetic energy. Thus, a warmer sample of water will have more kinetic energy (assuming the same mass). Therefore, the water molecules and anything that joins in with it will move at a faster rate. This perpetuates the spreading.
If you boil 100g of water should the steam weigh more than 100 grams?
If all the water boils off, the mass of the steam will be 100 grams. Matter cannot be created or destroyed.
Why is a piece of ice more effective in cooling a drink than the same mass of cod water?
Because the ice is colder than cold water.
What is advective cooling?
the process by which the temperature of an air mass decreases as the air mass moves over a cold surface.
What is the process by which the temperature of an air mass decreases as the air mass moves over a cold surface?
adibiatic cooling
Which holds more water vapor a warm air mass or a cold air mass?
A warm air mass and a cold air mass holds the same amount water vapor but the air mass is smaller
How would bigger mass in the water affect the cooling rate?
Say you are cooling liquid A with water. The rate of heat transfer is given by Q = mH2OCpH2OdTH2O = mACpAdTA, where m is the mass, Cp is the mean heat capacity and dT is the change in temperature. So, if you increase m, the mass of water, Q increases (the rate of heat transfer increases) and hence the cooling rate would increase. And if m were to be decreased, the cooling rate would decrease. Strictly speaking, it should be the mass flowrate and not the mass that would be the parameter.
When water vapor forms a cloud does the water vapor get warmer or colder?
Cooler. The cloud forms because the water vapor condenses by cooling down. Thunderstorms occur because a warm, moist air mass is cooled by an incoming cold air mass. When the moist air gets chilled, the water vapor condenses to form clouds, resulting in rain.

An air mass that forms over water at a low latitude is most likely cold or hot?
Cold and Humid
If a mass of ocean water is cold and salty what will it do?
The cooler saltier water sinks toward the ocean floor.
