Quizplus · Accepted Answer

Increased air pressure on the surface of hot water tends to prevent boiling. This is because boiling occurs when the vapor pressure of the liquid exceeds the atmospheric pressure above it. When the air pressure is increased, the atmospheric pressure increases, which makes it more difficult for the liquid to boil. This is why it takes longer to boil water at high altitudes where the air pressure is lower. So, the answer is (A) prevent boiling.
