Explanation:
Answer: The given statement is true.
Explanation:
Boiling point is defined as the point at which vapor pressure of a substance becomes equal to atmospheric pressure. During this point, the liquid changes into vapor state and temperature remains constant till all the liquid changes into vapor state.
Vapor pressure is defined as the pressure exerted by vapors or gas on the surface of a liquid.
Thus, we can conclude that the statement if the vapor pressure of a liquid is less than the atmospheric pressure, the liquid will not boil, is true.
