Use the table to answer the question. A student adds ice to several samples of water. The results are shown in the table. Which conclusion can be drawn from the results?

Responses

• As the amount of ice added decreases, the temperature decreases

• As the temperature increases, the kinetic energy of the water decreases

• As the temperature decreases, the kinetic energy of the sample increases

• As the amount of ice added increases, the change in temperature increases
