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.
