Question

multiple choice 1 point a student thinks that water will evaporate faster in a warm place than in a cool one. they want to do an experiment to find out if they are correct. they have two identical buckets of water. which of the following should they do? place a bowl of water in a cool place and a bowl with twice the amount of water in a warm place. place two bowls with the same amount of water in a warm place. place a bowl of water in a cool place and a bowl with half of the amount of water in a warm place. place a bowl of water in a cool place and a bowl with the same amount of water in a warm place.

Explanation:

Step1: Recall evaporation principle

Evaporation rate of water depends on temperature. Higher - temperature environments increase evaporation rate. To test the hypothesis that water evaporates faster in warm place, we need to keep other factors (like amount of water) constant.

Step2: Analyze options

• Option 1: Different amounts of water in warm and cool places won't isolate the effect of temperature on evaporation.
• Option 2: Different amounts of water in warm and cool places won't isolate the effect of temperature on evaporation.
• Option 3: Keeping the amount of water the same and placing in warm and cool places respectively can test the hypothesis as it only changes the temperature factor.
• Option 4: Different amounts of water in warm and cool places won't isolate the effect of temperature on evaporation.

Answer:

Place two bowls with the same amount of water in a warm place and a bowl of water in a cool place.
