What else can I help you with?
Can you predict the boiling point of a substance under unchanging pressure?
No. Determining the boiling point at any pressure is normally done experimentally.
If the boiling point of a certain amount of a liquid is 150 degrees then what is the boiling point of twice that amount of the liquid?
The boiling point of twice the amount of liquid will remain 150 degrees. The boiling point of a substance is determined by the chemical properties of the substance itself, rather than the quantity of the substance.
What do the terms 'boiling' and 'simmering' mean?
Boiling is heating any liquid substance over its boiling point, till it changes its state.. Simmering is continuously heating any liquid substance to keep it hot..
Is boiling point a chemical property?
Yes, boiling point is a chemical property. It is the temperature at which a substance changes from a liquid to a gas phase under standard atmospheric pressure, and is characteristic of that substance, making it a chemical property.
Does boiling point and melting point occur at the same temperature?
It depends on the substance and the pressure. For most substances at atmospheric pressure, the boiling point is much higher than the melting point. However, some things, like nitrogen and carbon dioxide, do not have any liquid phase at atmospheric pressure--they go directly from solid to gas and vice-versa.
What substance has the lowest boiling point?
Helium has the lowest boiling point of any known substance, at -268.9 degrees Celsius.
What is the boiling point of any substance?
The boiling point of a substance is the temperature at which its vapor pressure equals the atmospheric pressure, causing it to change from a liquid to a gas. The boiling point varies depending on the substance and the external pressure.
Can you predict the boiling point of a substance under unchanging pressure?
No. Determining the boiling point at any pressure is normally done experimentally.
If the boiling point of a certain amount of a liquid is 150 degrees then what is the boiling point of twice that amount of the liquid?
The boiling point of twice the amount of liquid will remain 150 degrees. The boiling point of a substance is determined by the chemical properties of the substance itself, rather than the quantity of the substance.
What do the terms 'boiling' and 'simmering' mean?
Boiling is heating any liquid substance over its boiling point, till it changes its state.. Simmering is continuously heating any liquid substance to keep it hot..
For any pure substance the boiling point and melting point will always remain?
The melting point and the boiling point of a substance are physical characteristics for each substance and are unchanged at the same pressure.
The temperature at which a given substance will change from a liquid into a gas?
The temperature in which a given substance will change from a liquid to a gas is its boiling point. Every element, compound and mixture has a different boiling point. Use an SI data book or the internet to find the boiling point of a particular suubstance.
How can boiling point be used to find out if a substance is pure?
At Boiling Point all the material evaporates leaving no residue which means it is pure. But if it leaves some residue after evaporating at boiling point then it is not pure. For example : If you take an example of pure water & Saline Water then pure water will evaporate at its boiling point leaving nothing after it. But Saline water evaporates leaves salt behind it.
How are evaportion and boiling different?
Evaporation occurs at the surface of a liquid at any temperature as long as the substance is a liquid. Boiling occurs throughout the liquid and occurs at the boiling point.
Does a physical property describes a boiling point?
The boiling point of any given material is indeed among its physical properties.
Is boiling point a chemical property?
Yes, boiling point is a chemical property. It is the temperature at which a substance changes from a liquid to a gas phase under standard atmospheric pressure, and is characteristic of that substance, making it a chemical property.
Is there any relation between boiling point and refractive index?
No, there is no direct relationship between the boiling point and refractive index of a substance. Boiling point is a physical property related to the temperature at which a substance changes from a liquid to a gas, whereas refractive index is a measure of how light propagates through a material.
