Question 1 Report

Which of the following statements correctly defines the boiling point of a liquid? The temperature at which the

saturated vapour pressure equals the atmospheric pressure

molecules leaves the liquid at a rate equal to the rate at which they return

molecules leave the liquid at a rate higher than that at which they return

molecules leave the liquid at a rate lower than the rate at which they return

Answer Details

The boiling point of a liquid is the temperature at which its saturated vapor pressure becomes equal to the atmospheric pressure. At this temperature, the molecules of the liquid gain enough energy to overcome the intermolecular forces holding them together and escape into the atmosphere as vapor. As the vapor pressure increases, it eventually reaches the same level as the atmospheric pressure, causing bubbles to form throughout the liquid and resulting in the characteristic boiling behavior. correctly defines the boiling point of a liquid.
