Yes, a pure substance boils at a fixed temperature under a specific pressure. This boiling point is characteristic of the substance and remains constant as long as the pressure is maintained. However, if impurities are present or if the pressure changes, the boiling point can vary.

What liquid evaporates at 120 degrees Celsius?
Any substance which is liquid at that temperature. Liquids evaporate at any temperature. If you mean boiling, which happens at a fixed temperature at fixed pressure, then nitric acid fits.
How can a substance boil to a higher temperature with the same rate of heat provided?
A substance can boil at a higher temperature when the external pressure is increased. This phenomenon is seen in pressure cookers, where the higher pressure raises the boiling point of water. The substance requires more energy to overcome this increased pressure and reach the higher boiling temperature.
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.
The freezing point and boiling point for matter is a constant Explain this meaning of constant?
It means that the freezing or melting points do not change, that they are always the same, depending on the type of matter. For eg. the melting point or freezing point of water is 0○ Celsius and the boiling point is always 100○C.
How is evaporation different from boiling water?
You boil a substance to evaporate the liquid.
What liquid evaporates at 120 degrees Celsius?
Any substance which is liquid at that temperature. Liquids evaporate at any temperature. If you mean boiling, which happens at a fixed temperature at fixed pressure, then nitric acid fits.
What is the effect of soluble volatile substance on the boiling point of a water solution?
A soluble volatile substance will lower the boiling point of a solution. The volatile substance will boil at a lower temperature than the water component, thus causing the solution to boil at a lower temperature.
How can a substance boil to a higher temperature with the same rate of heat provided?
A substance can boil at a higher temperature when the external pressure is increased. This phenomenon is seen in pressure cookers, where the higher pressure raises the boiling point of water. The substance requires more energy to overcome this increased pressure and reach the higher boiling temperature.
What two ways can make something boil?
Something can boil by increasing the temperature of the substance until it reaches its boiling point, causing the liquid to evaporate and form bubbles. Another way to make something boil is by decreasing the surrounding pressure, which lowers the boiling point of the substance and allows it to boil at a lower temperature.
Why does the temperature remain constant when it boils?
A substance has different phases, but it only boils at a certain temperature. If it is over that temperature it will evaporate or if it is under that temperature it won't boil.
What remains constant when a substance starts to boil?
Temperature! :) doing a crossword puzzle on it right now!
What is boil in science?
Every liquid has a temperature and pressure at which the substance gives off vapor internally. The temperature and pressure at which this occurs is called the boiling point. The term "boil" means what happens at these points.
What temperature does every pure substance boil at?
The boiling temperature of a pure substance is unique and specific to that substance. It is determined by its molecular structure and strength of intermolecular forces. This characteristic boiling temperature is referred to as the substance's normal boiling point.
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 is the definition of saturation temperature and how does it relate to the behavior of a substance at its boiling point?
Saturation temperature is the temperature at which a substance transitions between its liquid and vapor phases at its boiling point. At this temperature, the substance is in equilibrium between its liquid and vapor states. When a substance reaches its saturation temperature, any additional heat added will cause it to boil and transition completely into vapor.
How would you know whether a chemical is pure or impure?
An inpure chemical boil over a range of temperature. While, a pure solution melt at a fixed temperature.
Is it true that a liter of gasoline will boil at the same temperature as a milliliter of gasoline?
Yes, as boiling point is a property of the substance.
