(1 point)
Responses
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 amount of ice added decreases, the temperature decreases.
As the amount of ice added decreases, the temperature decreases.
As the temperature increases, the kinetic energy of the water molecules decreases.
As the temperature increases, the kinetic energy of the water molecules decreases.
As the temperature decreases, the kinetic energy of the sample increases.

Question 2: The correct conclusion that can be drawn from the results is "As the amount of ice added increases, the change in temperature decreases." This is because as more ice is added, it absorbs more heat from the water, causing the temperature to decrease.
Question 3: The independent variable in this investigation is the "amount of ice cubes added." This is because the student is manipulating and varying the amount of ice added to each sample to observe its effect on the change in temperature.
Question 4: The graph of the relationship between temperature and kinetic energy in one phase of matter would be a diagonal line. This is because as temperature increases, kinetic energy also increases in a direct and proportional manner.
