Question

connor looks at his backyard after a rainstorm. he notices that the large, shallow puddles have mostly evaporated but the smaller, deeper puddles remain. he wonders what factors might affect the evaporation rate of water. he has the following supplies available: tap water, distilled water, a wide heat - safe dishpan, a narrow heat - safe glass, a hot plate, a stopwatch. using only these supplies, which questions can connor investigate with an experiment? select all that apply. does tap water evaporate more quickly when it is heated on a hot plate? does distilled water evaporate more quickly than tap water? does tap water dissolve more salt when it is heated on a hot plate? does tap water evaporate more quickly from a wide container than from a narrow one?

Explanation:

1. For "Does tap water evaporate more quickly when it is heated on a hot plate?", he can use tap - water, hot plate and stopwatch to measure evaporation time with and without heating.
2. For "Does distilled water evaporate more quickly than tap water?", he can use both types of water, a container and stopwatch to compare evaporation times.
3. For "Does tap water dissolve more salt when it is heated on a hot plate?", there is no salt in the supplies, so this cannot be investigated.
4. For "Does tap water evaporate more quickly from a wide container than from a narrow one?", he can use tap - water, wide and narrow containers and stopwatch to compare evaporation times.

Answer:

A. Does tap water evaporate more quickly when it is heated on a hot plate?
B. Does distilled water evaporate more quickly than tap water?
D. Does tap water evaporate more quickly from a wide container than from a narrow one?
