Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The statement is false. The average human body at rest produces about 100 watts of heat energy. In 30 minutes, this equals roughly 180,000 joules, which is insufficient to boil half a gallon (about 1.9 liters) of water from room temperature. Boiling that amount of water would require significantly more energy.
