A) It is a surface phenomenon
B) The vapor pressure of the liquid is less than atmospheric pressure at its boiling point.
C) The vapor pressure of the liquid is equal to atmospheric pressure at its boiling point.
D) The vapour pressure of the liquid is more than atmospheric pressure at its boiling point.​

Answer 1

Answer:

"As a liquid is heated, its vapor pressure increases until the vapor pressure equals the pressure of the gas above it. ... In order to form vapor, the molecules of the liquid must overcome the forces of attraction between them. The temperature of a boiling liquid remains constant, even when more heat is added."

Answer 2
