A student adds ice to several samples of water. The results are shown in the table.
Which conclusion can be drawn from the results?
(1 point)
As the temperature increases, the
• kinetic energy of the water molecules decreases.

Answer 1

The conclusion that can be drawn from the results is that as the amount of ice added increases, the final temperature of the water decreases. In the table provided, as you add ice to the water samples, the final temperatures recorded show a trend toward lower temperatures.

So, a more appropriate conclusion would be:

As the amount of ice added increases, the final temperature of the water decreases.

This reflects the principle of heat transfer, where the heat from the warmer water is absorbed by the ice (which is at 0°C or lower), causing the water temperature to drop. The statement you provided ("As the temperature increases, the kinetic energy of the water molecules decreases") is not supported by the data or the context of the experiment.
