The boiling point is when vapor pressure equals liquid pressure, phase changing from liquid to gas. Different liquids have varying boiling points based on intermolecular forces. Kinetic Molecular Theory explains phase change at boiling point.
Boiling Point: The boiling point of a substance is the temperature at which its vapor pressure equals the pressure on the liquid, and a phase change from liquid to gas occurs.
Factor for Boiling Times: The factor that should change when comparing the boiling times of liquids is A. The type of liquid inside the boiling vessel. Different liquids have different boiling points due to variations in their intermolecular forces.
Kinetic Molecular Theory: This theory explains why water changes phase at its boiling point by attributing it to the energy overcoming intermolecular forces, causing the transition from liquid to gas.
