During a science experiment, Ronnie raises the temperature of his solution by 25 degrees. Overnight, the temperature of his solution falls 20 degrees. Which of the following explains what Ronnie can do to make the net change of the temperature equal to zero degrees?

A. The net change is already zero since the temperature went up and down.

B. There is nothing that Ronnie can do tomake the net change of zero because the first two changes were different amounts.

C. Ronnie can cool the solution so that the temperature drops an additional 5 degrees.

D. Ronnie can heat the solution so that the temperature rises an additional 5 degrees.
