Question

Jenny predicts that when water in a cup evaporates, the mass of the water and cup together will get smaller.

Answer 1

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.
