The stronger the intermolecular forces in a liquid, the higher the boiling point.

The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to transition into a gas. It is a physical property specific to each substance and can be affected by factors such as pressure and impurities. The boiling point can be used to identify and characterize different substances.
The temperature at which a liquid boils is called its boiling point.
The point at which a liquid changes to gas is called the boiling point. It is the temperature at which the vapor pressure of the liquid is equal to the atmospheric pressure.
Boiling point is the temperature in which a substance in a liquid state turns to a gas state. In a pure substance (an element or 1 compound) that temperature is a unique property. For example, pure water boils at 100 degrees Celsius. Methanol has a boiling point of 64.7 degrees Celsius. In pure substances the temperature time graph makes a plateau. The boiling point is the same as the condensation point (where a gas turns into a liquid) for that substance.
The boiling point of liquid sodium (Na) is approximately 883°C (1621°F).
The boiling point of a liquid can change with air pressure. As air pressure decreases, the boiling point of a liquid also decreases, meaning it will boil at a lower temperature. Conversely, as air pressure increases, the boiling point of the liquid increases, requiring a higher temperature to boil.
