As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point.
A liquid boils when its vapor pressure equals atmospheric pressure.
What else can I help you with?
Why must the boiling point be measured at constant atmospheric pressure?
Boiling point is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure. By measuring at constant atmospheric pressure, we ensure consistency in the comparison of boiling points between different substances. Changing the pressure can alter the boiling point of a substance, so maintaining a constant pressure allows for accurate and meaningful comparison of boiling points.
What can change the boiling point of water?
The boiling point of water can be affected by changes in atmospheric pressure. At higher altitudes where the atmospheric pressure is lower, the boiling point of water is lower. Conversely, at lower altitudes with higher atmospheric pressure, the boiling point of water is higher.
Is it true that the boiling point of a liquid remains constant at all altitudes?
No. Atmospheric pressure falls the higher you go. The boiling point of a liquid varies with ambient pressure. If the pressure is lower then the boiling point will be lower.
What is the temp of boiling water at atmospheric pressure on the kelvin scale?
373 kelvin 100 celsius kelvin is basically celsius + 273
What is the point at which a liquids vapor pressure equals the atmospheric pressure?
This temperature is called the boiling point, and indicates the temperature at which a liquid will assume a gaseous state, given the addition of the heat of vaporization.That is the boiling point.
What is the relationship between pressure and the boiling points of liquid?
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
Why must the boiling point be measured at constant atmospheric pressure?

Changing the pressure can alter the boiling point of a substance, so maintaining a constant pressure allows for accurate and meaningful comparison of boiling points.
What is the relationship of boiling point with atmospheric pressure?
The boiling point of a substance decreases as the atmospheric pressure decreases. This is because lower atmospheric pressure reduces the pressure pushing down on the liquid, making it easier for the liquid to vaporize. Conversely, higher atmospheric pressure increases the boiling point of a substance as more pressure is needed to overcome the atmospheric pressure and cause the liquid to vaporize.
How does the boiling point different from lowland and highland?
The boiling point of a substance is lower at higher altitudes due to lower atmospheric pressure, which reduces the pressure exerted on the liquid. In contrast, at low altitudes with higher atmospheric pressure, the boiling point is higher as more pressure is needed to overcome atmospheric pressure.
As external pressure such as atmospheric pressure on liquid increases its boiling temperature?
At high pressure the boiling point is higher.
What is the relationship between the normal boiling point and vapor pressure of a substance?
The normal boiling point of a substance is the temperature at which its vapor pressure equals the atmospheric pressure. In other words, the higher the vapor pressure of a substance, the lower its normal boiling point will be.
Do all the liquids at their boiling points have same vapour pressure?
At the same atmospheric pressure, yes. That's kind of the definition of boiling point: when the vapor pressure is the same as the atmospheric pressure.
What is the relation between the altitude compared to sea level and the boiling point of water?
In general, the higher the altitude, the lower the pressure, and the lower the pressure the lower the boiling point.
How does atmospheric pressure affect the boiling point of matter?
Atmospheric pressure exerts pressure on the molecules of the liquid, confining them. In order to boil, the electrons must be excited, but must become hotter to overcome the pressure of the atmosphere. Therefore, pressure makes a liquid boil at a higher temperature. With a solid, the molecules are already compact together and have to be melted before they can be boiled. This does not require excitation of electrons, but it does require movement of electrons. Once the solid is melted, pressure will make it harder for the electrons to become excited.
What term defines the temperature at which the vapor pressure of the liquid equals the atmospheric pressure?
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
What is the condition which occurs when the atmospheric pressure is equal to the vapour pressure?
boiling
What is the relation between pressure and the boiling point of liquid?
The lower the atmospheric pressure, the lower the boiling point of the liquid. For example, at sea level, water boils right at 100 degrees Celsius, but at a high elevation where the atmospheric pressure is lower, the water will boil at below 100 degrees Celsius. This is why some recipes have high-altitude directions, allowing for this property.The higher the air pressure, the higher the temperature of the boiling point.The lower the air pressure is, the lower the temperature of the boiling point.In fact, in very high places like Mt Everest, the boiling point of water is so low that it is difficult or impossible to cook food.
