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.
Which refrigerant has the highest boiling temperatures at atmospheric pressure?
The refrigerant plays a key role in achieving vapor cycle air ... After that, and until all the water has been evaporated, the remaining boiling liquid stays at the ... of the higher temperature of boiling resulting from increased pressure.
How does pressure affect boiling points of substances?
Pressure significantly affects the boiling points of substances because boiling occurs when a liquid's vapor pressure equals the surrounding atmospheric pressure. At higher pressures, more energy is required for the vapor pressure to reach that point, resulting in a higher boiling point. Conversely, at lower pressures, such as at high altitudes, liquids boil at lower temperatures since the atmospheric pressure is reduced. This relationship is described by the Clausius-Clapeyron equation, which illustrates how changes in pressure influence phase transitions.
What temperature does water boil and evaporates into steam?
boiling point is a property which depends upon the atmospheric pressure. when vapour pressure of water is equal to external is called its boiling point.. if pressure is equal to atmospheric pressure ,boiling point is 100 degree celcius.
What factor besides temperature affects the boiling pointof water?
Besides temperature, atmospheric pressure significantly affects the boiling point of water. At higher elevations, where atmospheric pressure is lower, water boils at a temperature lower than 100°C (212°F). Conversely, in a pressure cooker, where pressure is increased, water can boil at temperatures above 100°C. This relationship is explained by the fact that boiling occurs when the vapor pressure of the liquid equals the surrounding pressure.
What is the relationship of boiling point with atmospheric pressure?

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.
What refrigerant has the lowest boiling temperatures at atmospheric pressure?
R-502 has thelowestboiling temperature atatmosphericpressure. It can be boiled as low as -50 deg F before the boiling pressure goes into a vacuum.
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.
What are the temperatures for boiling water?
The boiling point of water is 100 degree celsius
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.
As external pressure such as atmospheric pressure on liquid increases its boiling temperature?
At high pressure the boiling point is higher.
Which refrigerant has the highest boiling temperatures at atmospheric pressure?
The refrigerant plays a key role in achieving vapor cycle air ... After that, and until all the water has been evaporated, the remaining boiling liquid stays at the ... of the higher temperature of boiling resulting from increased pressure.
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.
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.
How does pressure affect boiling points of substances?

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.
