question 56

Multiple Choice

Will wrapping a bottle in a wet cloth produce a cooler bottle than placing the bottle in a bucket of cold water?

• A)The cloth of cold water will cool the bottled water down through the transfer of thermal energy to the cloth, and then insulate it from being warmed by the surrounding air.
• B)A bottle in a bucket of water will be cooler since the thermal energy is transferred to billions of water molecules in the bucket of water.
• C)A bottle wrapped in wet cloth will cool by the evaporation of liquid from the cloth. As evaporation progresses, the average temperature of the liquid left behind in the cloth can easily drop below the temperature of the cool water that wet it in the first place.
• D)The cloth can cool the bottle of water down, but only until it reaches the temperature a few degrees below the surrounding atmosphere. After that, evaporation and condensation will reach equilibrium between the cloth and air.
