In liquids, molecules are close together while in gases, molecules are very far apart. As liquids are heated, temperature increases and the energy in the molecules increase. The molecular motion becomes so great that the intermolecular forces between molecules are interrupted. In other words, the molecules move so fast that they break free from the liquid and form a gas.

Polarity affects boiling temperature. The greater the intermolecular forces are, the higher the boiling temperature is because it takes more energy to overcome the intermolecular forces. Hydrogen bonding is a particularly strong type of intermolecular force. For example, water, which has hydrogen bonding, therefore needs a high temperature before the energy in the moving molecules are enough to overcome the strong hydrogen bonds. Molecules with hydrogen bonding have higher boiling temperatures than nonpolar molecules with weak London Dispersion Forces.

What is the relationship of boiling point with volatility?

boiling point and volatility are inversely proportion


Does the boiling point increase with molar mass?

Yes, generally speaking, the boiling point of a substance increases with its molar mass.


Does greater mass change boiling temp?

The boiling point is not changed.


What is the relationship between pressure and boiling point according to the formula?

The relationship between pressure and boiling point is described by the formula: T K m P. This formula shows that as pressure increases, the boiling point of a substance also increases.


What is the relationship between boiling point and vapor pressure?

The relationship between boiling point and vapor pressure is that as vapor pressure increases, the boiling point decreases. This is because higher vapor pressure means that the liquid molecules are more likely to escape into the gas phase, leading to a lower boiling point.


What is the relationship between boiling point and pressure?

The relationship between boiling point and pressure is that as pressure increases, the boiling point of a substance also increases. This is because higher pressure makes it harder for molecules to escape into the gas phase, requiring more energy to reach the boiling point. Conversely, lower pressure decreases the boiling point as it allows molecules to escape more easily.


What phase change involves gas becoming a solid?

Vaporization (in mass, at the boiling point) or evaporation (on the surface and under boiling point).

What is the relationship between the heat of vaporization and boiling point of a substance?

The heat of vaporization is the amount of energy needed to change a substance from a liquid to a gas at its boiling point. The higher the heat of vaporization, the higher the boiling point of the substance.


What is the relationship between pressure and the boiling point of water?

The relationship between pressure and the boiling point of water is that as pressure increases, the boiling point of water also increases. This means that water will boil at a higher temperature under higher pressure. Conversely, water will boil at a lower temperature under lower pressure.


Does larger mass of water have different boiling temperature?

No. A large mass of water will have the same boiling point as a smaller mass of water. Differences in pressure, however, will cause differences in boiling point. - - - - - It takes longer to boil a large amount of water than a small amount because it takes longer to heat it up.


What is the molar mass of acetic acid by elevation of boiling point method?

The molar mass of acetic acid can be determined using the elevation of boiling point method by measuring the change in boiling point of a solution of acetic acid relative to the boiling point of the pure solvent. By applying the equation ΔT = K_b * m, where ΔT is the change in boiling point, K_b is the ebullioscopic constant of the solvent, and m is the molality of the solution, the molar mass of acetic acid can be calculated using the formula MM = (RT2) / (K_b * ΔT), where MM is the molar mass of acetic acid, R is the gas constant, and T is the temperature in Kelvin.
