The boiling points of noble gases increase with increasing atomic number. Therefore, the order of increasing boiling points is helium < neon < argon < krypton < xenon < radon.
In fractional distillation, the substances in a mixture are heated to their boiling points. Different substances have different boiling points, so will be separated at different times. The answer to your question is simply because they have different boiling points.
The correct increasing order of evaporation is: water, alcohol, kerosene, petrol. Water evaporates the fastest due to its low boiling point, followed by alcohol, kerosene, and then petrol, which has the highest boiling point.
No, due to the fact that fractional distillation uses the difference in boiling points of liquids to seperate them, therefore in order to perform fractional distillation there should be a difference of at least 1degree centigrade
The boiling points of the two liquids must be different in order to effectively separate them by distillation. This allows one liquid to vaporize at a lower temperature and be collected as a separate distillate from the other liquid.

Carboxylic acid > alcohol > ester > hydrocarbon. Carboxylic acids have the highest boiling points due to hydrogen bonding between molecules. Alcohols have the next highest boiling points due to hydrogen bonding as well. Esters have lower boiling points because they do not form hydrogen bonds as strongly. Hydrocarbons have the lowest boiling points as they have no functional groups to facilitate intermolecular forces.

intermolecular forces are hard to overcome...apex
The boiling points of the two liquids must differ in order to be separated by fractional distillation. This technique relies on heating the mixture to separate the components based on their boiling points. The greater the difference in boiling points, the more effective the separation will be.

Chemicals in crude oil separate based on their boiling points. When crude oil is heated in a distillation column, the components with lower boiling points vaporize first and rise to the top of the column. As the temperature increases, components with higher boiling points gradually separate out at different levels in the column. This process is known as fractional distillation.
The solution is heated to the boiling point and the solvent is collected as its a gas condenses
Non-metals generally have low boiling points compared to metals. This is because non-metals have weaker intermolecular forces, such as van der Waals forces, that require less energy to overcome in order for the substance to change from a liquid to a gas.
