All pure liquids, such as water, H20, have constant boiling points at certain atmospheric pressures, which is helpful in determining the identity of an unknown liquid. Some liquids have constant boiling points that are not pure, such as nail polish remover, or ethyl acetate. Since it is a mixture of more than one pure liquid, it is not a pure liquid itself, but if always mixed in the same ratios, will have a constant boiling point.
What else can I help you with?
If sample of a liquid was boiled for twelve minutes During that time the boiling point remained constant and the volume was reduced to half Is the liquid a pure substance?
Yes, the fact that the boiling point remained constant during the entire boiling process suggests that the liquid is a pure substance. Additionally, the reduction in volume without a change in boiling point further supports this conclusion.
Does pure liquid boils at fixed temperature at a given pressure?
Yes, a pure liquid will generally boil at a fixed temperature at a given pressure. This temperature is known as the boiling point, and it remains constant as long as the pressure is constant.
Why is the temp of boiling pure acetone constant?
Acetone has a constant boiling point because it is an azeotrope. Azeotropes are mixtures of two or more liquids whose proportions cannot be altered by simple distillation. They are also called constant boiling mixtures.
What temperature at which a substance in the liquid phase transforms to the gaseous phase refers to the substances?
The temperature at which a substance in the liquid phase transforms to the gaseous phase is called the boiling point for pure substances. It is a characteristic property of the substance and remains constant under a specific pressure.
What temp will alcohol change from liquid into gas?
The boiling point of pure ethanol is 78,37 0C.
What is the term used to describe the constant temperature at which a pure liquid changes to vapour?
Boiling point

The difference between the boiling point of a liquid in pure state and the boiling point of the liquid in solution?
Boiling Point Elevation
Does pure liquid boils at fixed temperature at a given pressure?
Yes, a pure liquid will generally boil at a fixed temperature at a given pressure. This temperature is known as the boiling point, and it remains constant as long as the pressure is constant.
What test can differentiate solution and a pure liquid?
One test that can differentiate between a solution and a pure liquid is a boiling point test. A pure liquid will have a specific and consistent boiling point, while a solution will exhibit a boiling point elevation due to the presence of solute particles. By measuring the boiling points, you can determine if the substance is a solution or a pure liquid.
Why is the temp of boiling pure acetone constant?
Acetone has a constant boiling point because it is an azeotrope. Azeotropes are mixtures of two or more liquids whose proportions cannot be altered by simple distillation. They are also called constant boiling mixtures.

The temperature at which a substance in the liquid phase transforms to the gaseous phase is called the boiling point for pure substances. It is a characteristic property of the substance and remains constant under a specific pressure.
What is liquid's boiling point?
Boiling point is the temperature in which a substance in a liquid state turns to a gas state. In a pure substance (an element or 1 compound) that temperature is a unique property. For example, pure water boils at 100 degrees Celsius. Methanol has a boiling point of 64.7 degrees Celsius. In pure substances the temperature time graph makes a plateau. The boiling point is the same as the condensation point (where a gas turns into a liquid) for that substance.
How could a liquids boiling point be used to determine if it is a mixture or a pare substance?
pure substances have a distinct boiling point. Adding more heat just makes the substance boil faster but the temperature stays the same. A mixture does not have a distinct boiling point. Adding more heat will make the temperature increase.
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.
