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.

∙ 11y agoThe stronger the intermolecular forces, the higher the boiling point. When the forces are stronger it takes more energy (heat) to break them apart.

As the molecular mass of a nonpolar liquids increase the boiling points does what?
If the mass increases with the volume (ie if the density remains the same) then the boiling point remains constant. If the volume remains contstant with rising mass (ie greater density) then the boiling point increases.
What is the relationship of boiling point with atmospheric pressure?
The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, atmosphere
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.
Why is the boiling point of propyleamine higher than that of trimethyleamine?
it is because it has got higher mass
What is the relationship between the boiling point of the alcohol and the number of atoms in its molecules?
Alcohols are polar compounds. Now if the number of molecules is less the attraction is more and then the boiling point is high. Hence the relation.
What is the relationship of boiling point with volatility?
boiling point and volatility are inversely proportion
Does greater mass change boiling temp?
The boiling point is not changed.
What physical properties of the sample is most helpful to determine if the liquid is water color mass volume boiling point?
boiling point. (The Boiling point of water is 100 oC.)
As the molecular mass of a nonpolar liquids increase the boiling points does what?
If the mass increases with the volume (ie if the density remains the same) then the boiling point remains constant. If the volume remains contstant with rising mass (ie greater density) then the boiling point increases.
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 are 5 pysiacal properties?
mass, volume, density, melting point, boiling point
What is the relationship of boiling point with atmospheric pressure?
The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, atmosphere
How does polarising power effect boiling point?
Polar molecules have relatively weak intermolecular forces. Intermolecular forces and boiling point have a direct relationship, so due to the fact that polar molecules have weak forces, their boiling points will be lower.
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.
How are freezing point depression and boiling point elevation useful?
the main applicative use of freezing point depression and boiling point elevation is to calculate the molecular mass of a non volatile solute in a pure solvent.
What are three charictaristic property's of matter?
Matter is anything that has mass and occupies space. Now since it has mass and volume it has a density. The density again can lead to various states and these states lets us know the freezing and boiling points of matter. Thus density, boiling point and freezing point are the boiling point of matter.
Which physical properties water is measured?
Some examples include mass, volume, melting point, and boiling point.
