How does boiling point differ from normal boiling point?
The boiling point and normal boiling point are related concepts, but they have specific differences. Boiling Point: The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to change into a gas or vapor. At the boiling point, bubbles of vapor form within the liquid and rise to the surface, resulting in a continuous phase change from liquid to gas. Different substances have different boiling points, which can be influenced by factors such as atmospheric pressure and the strength of intermolecular forces within the liquid. Normal Boiling Point: The normal boiling point of a substance is the temperature at which it boils when the atmospheric pressure is at the standard pressure of 1 atmosphere (atm), which is equivalent to 101.325 kilopascals (kPa) or 760 millimeters of mercury (mmHg). This standard pressure is typically found at sea level.
What is melting points and the boiling points?
Melting point: the temperature at which a solid become a liquid. Boiling point: the temperature at which a liquid become a gas.
Are the boiling points higher temperature than the melting points?
yes, for the same molecule. However, some substances don't have a liquid phase and so the melting point is exactly the same as the boiling point at normal pressures (sublimation is the phase change from solid -> gas)
Why would a liquid have two different boiling points?
possibly if it has been contaminated by other substances (as compared to original boiling point - it seems as though it has 2 different boiling points) things such as sodium chloride (table salt) raise the boiling point of water and lower its melting point note though that a pure liquid can never have 2 different boiling points - the boiling point is a property of a a liquid and will never change no matter what. alternatively if the fluid concerned is a mix of 2 different liquids (eg. alcohol mixed in water) the liquid with the lower boiling point (eg. alcohol) will boil off first, then the remaining fluid will continue heating up until the 2nd boiling point is reached (eg. of water). thus the fluid seems to boil at 2 different temperatures
Are boiling points and freezing points checimal changes?
No, boiling points and freezing points are not chemical changes. They are physical properties of a substance related to its phase transition between solid, liquid, and gas states. Chemical changes involve the formation of new substances with different chemical properties.

What is the boiling point of any liquids?
Boiling points vary from liquid to liquid.

When two liquids in a mixture differ by their boiling points the best method to separate these liquids is?
The best method to separate liquids with different boiling points is fractional distillation. This process involves heating the mixture to its boiling point and then condensing the vapors back into liquid form based on their boiling points. The components with lower boiling points will vaporize first, allowing for their separation from the mixture.
Do all liquids have the same boiling and melting point?
No, different liquids have different boiling and melting points depending on their chemical composition. The boiling point is the temperature at which a liquid turns into a gas, while the melting point is the temperature at which a solid turns into a liquid. Each liquid has its own unique set of physical properties that determine its specific boiling and melting points.
What is the state of matter sodium is in at boiling point?
The state of matter is changing, as with any element. However, just before the temperature reaches boiling point, it is in a liquid phase. Just after, it is in a gaseous phase. Boiling points differ based on the element, so this will be true with any element chosen.
What do the term boiling point snd freezing point mean?
It means boiling points are hot and freezing points are cold.
What are Boiling points and freezing points examples of?
boiling points are when a substance starts to boil. example- water 32degrees F A boiling point is when a liquid evaporates to form a gas. freezing points are when a substance starts to freeze. example- water 212degrees F A liquid freezes to a solid below its freezing point.

How does the color of the distillate differ from the original liquid in the distilling flask?
The distillate tends to be colorless or lighter in color compared to the original liquid in the distilling flask. This is because the distillation process strips away impurities and separates the components based on their boiling points, resulting in a purer and clearer distillate. Any colored impurities or compounds with higher boiling points will be left behind in the distilling flask.
