Question

explain what happened to the water in the cups.

Explanation:

The sun provides heat energy to the cups of water over time. This heat causes the water to undergo evaporation, where liquid water turns into water vapor (visible as steam). By 6:00 PM, more water has evaporated compared to 6:00 AM, so the water level in the cups is lower.

Answer:

The water in the cups evaporated over time. The heat from the sun caused liquid water to turn into water vapor (the visible steam), reducing the amount of liquid water in each cup by 6:00 PM compared to 6:00 AM.
