Question

What happens if we change atmospheric pressure on boiling point?

• A. Higher atmospheric pressure results in lower BP
• B. No change
• C. Higher atmospheric pressure results in higher BP
• D. None of the choices

Answer 1

The correct option is C

Higher atmospheric pressure results in higher BP

A liquid boils when its most energetic molecules form bubbles of vapor. Under sufficiently high air pressure, however, a liquid becomes hot but does not boil or evaporate.

Higher atmospheric pressure results in higher BP & Lower atmospheric pressure results in lower BP
