The normal boiling point of ethanol is 78.4 degrees C and, at this temperature, the vapor pressure is 101,325 Pascals (Pa) or 760 manometric units (mm Hg), which is a pressure measurement using a millimeter of Mercury.

Defined as the point as which liquids vapor pressure equals the atmospheric pressure?

The normal boiling point(also called the atmospheric boiling point or the atmospheric pressure boiling point)is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure at sea level, 1 atmosphere.The normal boiling point of water is about 100 degrees Celsius at a pressure of 1 ATM (i.e., 101.325 kPa).General Useful Information:The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the environmental pressure, but the environmental pressure may or may not be equal to the atmospheric pressure at sea level, 1 ATM.If the surrounding environmental pressure is less than atmospheric pressure, then the boiling point is less than the normal boiling point.If the surrounding environmental pressure is greater than atmospheric pressure, then the boiling point is greater than the normal boiling point.At the boiling point, adding enough heat to the liquid will cause the liquid to vaporize (that is boil or form a gas).


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.


What is the relationship between presssure and the boiling point of Liquids?

Boiling point is nothing but point at which liquid starts changing from liquid state to vapor state. liquid changes to vapor when vapor pressure equal to surrounding pressure. so if surrounding pressure is less boiling point is less and boiling point is high if surrounding pressure is high this point is on view of pressure


Does reduced vapor pressure at high altitudes causes a liquid to boil at a higher temperature?

Yes, reduced vapor pressure at high altitudes leads to a lower boiling point for liquids, not a higher one. This is because reduced pressure means there is less pressure pushing down on the liquid, making it easier for it to vaporize and boil at a lower temperature.


How can one determine the normal boiling point by using the vapor pressure and temperature?

To determine the normal boiling point using vapor pressure and temperature, one can plot a graph of vapor pressure versus temperature and identify the temperature at which the vapor pressure equals the standard atmospheric pressure of 1 atm. This temperature corresponds to the normal boiling point of the substance.

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.

What is the vapor pressure a liquid at its normal boiling temperature?

Vapor pressure of a liquid at its normal boiling temperature is simply the atmospheric pressure, aka 1 atm, 760 torr, etc. This is by definition.


How does boiling point differ from normal boiling point?

The boiling point and normal boiling point are related concepts, but they have specific differences. Boiling Point: The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to change into a gas or vapor. At the boiling point, bubbles of vapor form within the liquid and rise to the surface, resulting in a continuous phase change from liquid to gas. Different substances have different boiling points, which can be influenced by factors such as atmospheric pressure and the strength of intermolecular forces within the liquid. Normal Boiling Point: The normal boiling point of a substance is the temperature at which it boils when the atmospheric pressure is at the standard pressure of 1 atmosphere (atm), which is equivalent to 101.325 kilopascals (kPa) or 760 millimeters of mercury (mmHg). This standard pressure is typically found at sea level.


How does normal boiling points differ from other boiling points of the same liquid?

The normal boiling point is the boiling point at sea level, or more precisely, at 1 atmosphere pressure. At higher elevations, or at lower atmospheric pressures, the boiling point is lower. At higher atmospheric pressures, the boiling point is higher.


The reduced vapor pressure at high altitudes causes a liquid to boil at a?

The higher the vapor pressure of a liquid at a given temperature, the lower the normal boiling point (i.e., the boiling point at atmospheric pressure) of the liquid.

Is it possible for a liquid to boil at a temperature other than its normal boiling point?

Yes, it is possible for a liquid to boil at a temperature other than its normal boiling point under specific conditions, such as changes in pressure or the addition of solutes. These factors can alter the boiling point of a liquid, causing it to boil at a higher or lower temperature than normal.


What it the scientific definition normal boiling point?

The Boiling Point is the point at which a substance at liquid state boils. The temperature that the liquid has to reach to be at Boiling Point (B.P) ranges, it is different for each liquid. The B.P for water is 100 degrees Celsius.
