A student adds ice to several samples of water. The results are shown in the table. Which conclusion can be drawn from the results? and answers are this
As the temperature decreases, the kinetic energy of the sample increases.
As the temperature decreases, the kinetic energy of the sample increases.
As the amount of ice added decreases, the temperature decreases.
As the amount of ice added decreases, the temperature decreases.
As the amount of ice added increases, the change in temperature increases.
As the amount of ice added increases, the change in temperature increases.
As the temperature increases, the kinetic energy of the water molecules decreases.
