A. Use a scale to measure the mass of a cup of water. Leave the cup out for one day and measure the mass again.
Explanation:
Jenny can predict is evaporation occurs by using a weighing scale to measure that mass of a cup of water, then he leaves the cup out for one day and he measures the mass again.
If the mass remains the same, then evaporation did not occur.
If evaporation occurs, then the mass will be lesser after the second measurement.
From this Jenny can infer the mass loss and made good deductions.
Evaporation is a phase change in which liquid turns to vapor.
He experiences them because he still has more to learn. He takes those failures, and use them to his advantage. He gets better at what he's doing by learning from the failures and mistakes.
