Boiling point of NH3: -33,34 0C
Boiling point of NF3: -129,1 0C
The boiling point of ammonia is higher.
Sodium fluoride has a higher boiling point than lithium fluoride due to stronger intermolecular forces of attraction between sodium and fluoride ions in sodium fluoride compared to lithium and fluoride ions in lithium fluoride. This stronger bond requires more energy to break, leading to a higher boiling point for sodium fluoride.
Concentrated. concentrated solutions is completely ionized. The colligative property that is boiling-point states that it will increase as the number of particles increases. Diluting a concentrated substance lessens the number of particles making it obviously lower in bp
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.
Boiling is the temperature at which a substance changes from a liquid to a gas. It is not necessarily the maximum temperature a substance can reach, as some substances can be heated to higher temperatures without boiling.
Boiling is dependent on pressure because the pressure affects the boiling point of a substance. When the pressure is higher, the boiling point of a substance is also higher, and when the pressure is lower, the boiling point is lower. This is because pressure affects the vapor pressure of the substance, which needs to equal the atmospheric pressure for boiling to occur.
Sodium chloride has a higher boiling point.
If the impurity has a higher boiling point then the boiling point of the mixture will also be slightly higher, and vice versa.

Hydrogen fluoride has higher boiling point than hydrogen bromide ( HF 19.5 C HBr -66 C) because in hydrogen fluoride has two kinds of forces, one is hydrogen bonding and other is London dispersion forces. In Hydrogen bromide there are only london dispersion forces. These are weaker than hydrogen bonds therefore HF has the higher boiling pint.
A substance can boil at a higher temperature when the external pressure is increased. This phenomenon is seen in pressure cookers, where the higher pressure raises the boiling point of water. The substance requires more energy to overcome this increased pressure and reach the higher boiling temperature.
The boiling point is typically higher than the melting point for a substance. The boiling point is the temperature at which a substance transitions from a liquid to a gas, while the melting point is the temperature at which a substance transitions from a solid to a liquid.
The normal boiling point of a substance is the temperature at which its vapor pressure equals the atmospheric pressure. In other words, the higher the vapor pressure of a substance, the lower its normal boiling point will be.
