Question

The boiling point of a liquid increases when there is a ________________.

• A. decrease in atmospheric pressure.
• B. increase in atmospheric pressure
• C. no change in atmospheric pressure
• D. increases in mass of liquid.

Answer 1

The correct option is B increase in atmospheric pressure

At higher elevations, when the atmospheric pressure is much lower, the boiling point is also lower. The boiling point increases with increased pressure up to the critical point, where the gas and liquid properties become identical.
