Max's teacher demonstrated a scientific principle in class. She placed a plate that had been in the freezer on the table, and she had the students touch the plate to show that it was cold. She then placed a cup of hot water on the plate and had the students touch the cup to show that it was hot. After five minutes, she removed the cup and let the students touch the cup and touch the area of the plate where the cup had been. The students said that the cup felt cooler and the plate felt warmer where the cup had been. Which of these statements best describes what teacher is demonstrating to the students?

• A. Hot objects cool down quickly.

• B. Cool objects warm up quickly.

• C. Heat moves from hot objects to cold objects.

• D. Heat moves from cold objects to hot objects.
