Sublimation is the direct change of a substance from a solid to a gas without passing through the liquid phase, while boiling is the conversion of a liquid to a gas by heating the liquid to its boiling point. Sublimation typically occurs at lower temperatures and pressures compared to boiling.

Is it true that sublimation and boiling both happen at the surface of the substance?
No, sublimation occurs when a solid turns directly into a gas without passing through the liquid phase, while boiling occurs when a liquid turns into a gas. Sublimation can happen at the surface of a solid, while boiling happens within the liquid as bubbles of gas form throughout the substance.
Can sublimation extraction decantation filtration or evaporation be used to separate the elements found in a compound?
Yes, sublimation can separate a mixture based on differences in volatility. Extraction can separate compounds based on differences in solubility. Decantation separates solid particles from a liquid phase. Filtration separates a solid from a liquid or a gas. Evaporation separates a solute from a solvent based on differences in boiling points.
The boiling point of both the liquids should be known during separation by fractional distillation method.why?
Knowing the boiling points of the liquids is important during fractional distillation because the process relies on differences in boiling points to separate the components. By knowing the boiling points, the distillation can be conducted at the appropriate temperature to ensure efficient separation of the components based on their boiling point differences.
What does fractional distillation rely on?
Fractional distillation relies on the differences in boiling points of the components in a mixture. By heating the mixture to a specific temperature, the component with the lowest boiling point will vaporize first and can be collected, leaving behind the higher boiling point components in the distillation flask.
Do Sublimation and boiling both happen at the surface of the substance.?
Sublimation occurs when a solid transitions directly to a gas without passing through the liquid phase, typically at the surface of the solid. Boiling, on the other hand, occurs when a liquid transitions to a gas throughout the bulk of the liquid, not just at the surface.
Which of these phase changes does not involve changing a liquid into a gas sublimation or vaporization or evaporation or boiling?
sublimation
How does boiling differ from evaporantion?
the difference between sublimation and boiling is that sublimation is that a solid changes to a gas and boiling is that liquid changes to a gas and that's my answer guys by.
Do sublimation and boiling both happen at the surface of the substance?
False
What does changes in matter mean?
Examples are: freezing, liquefaction, sublimation, boiling.

What is theory on distillation?
Distillation is based on the differences between boiling points of the components of a liquid.
