A cup of milk is placed in a microwave oven. Consider these statements: (1) Only the milk will be heated. (2) The cup will remain cool. (3) Both the cup and the milk will get hot. Which one is false?
Correct answer A. 3
Explanation
Microwaves at about 2.45 GHz are absorbed by water molecules in the milk, while a microwave-safe cup absorbs little energy and stays fairly cool, so statement 3 is false.
