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

The best conclusion that can be drawn from the results is:
As the amount of ice added increases, the change in temperature increases.
This is indicated by the samples, where larger amounts of ice correspond to a more significant decrease in temperature in the water.
The independent variable in this investigation is:
ice cubes added.
This is because the student is changing the amount of ice to observe its effect on the final temperature of the water samples.
The graph of the relationship between temperature and kinetic energy in one phase of matter would look like:
a diagonal line.
As temperature increases, the kinetic energy of the particles in that phase of matter also increases, indicating a direct linear relationship.
