When an object is refrigerated:

When an object is refrigerated:

• A. some of its heat energy is destroyed.
• B. heat is removed from it.
• C. more cooling is added.
• D. its molecules move faster.

Answer: (B)

Refrigeration works by transferring heat away from the object to its surroundings. Heat is not destroyed; energy simply moves from the object into the cooler environment, so the object's temperature drops. The idea of “adding more cooling” isn’t the right description—the system removes heat, not adds something extra to cool. As the object loses heat, its molecules slow down, not speed up, which is why it becomes colder.
