The boiling point of water depends upon:

by

(A) Atmospheric pressure
(B) Volume
(C) Mass
(D) None of these

🧠 Explanation:

  • The boiling point of water is primarily affected by the atmospheric pressure.
  • At sea level (1 atmosphere), water boils at 100°C, but at higher altitudes where pressure is lower, it boils at a lower temperature.
  • Neither the volume nor the mass of water significantly changes its boiling point under constant pressure.
  • Therefore, the correct answer is (A) Atmospheric pressure.
