Question

mitch did an experiment about evaporation for the school science fair. on saturday morning, he set a beaker of water outside. during the course of the day, the temperature rose, stayed constant at a high temperature, and then cooled back down. he discovered that the water evaporated more quickly when the outdoor temperature was hotter. which graph could show the amount of water in the beaker over the course of the day?

Explanation:

Step1: Understand evaporation

Evaporation causes water to turn into vapor, reducing water amount.

Step2: Analyze temperature effect

Higher temperature speeds up evaporation. As time passes, water amount in beaker decreases due to evaporation throughout the day. So the graph of water amount in beaker over time should be a decreasing - function, which is the first graph.

Answer:

The first graph (the one with a decreasing - curve)
