Water actually has a higher boiling point than most all alcohols. Alcohols have less adhesion to their own molecules, being larger in molecular weight and in total atoms (at least 6 atoms, starting with methanol, and then adding 3--2 hydrogen and 1 Carbon--for each subsequent Carbon atom addition) than water (3--2 hydrogen and 1 oxygen). Water is highly polar, and smaller alcohols are also polar, but with the addition of Carbon atoms, this attribute decreases in strength. Since water is so small, and so polar, is harder to activate into a gaseous state, all levels of pressure being equal.

What is the relationship between the altitude and the boiling point?
The boiling point of water will be greatest at that point on Earth that is the closest to sea level. Boiling point of water depends on the atmospheric pressure. The boiling point of water varies depending on the weather. At low atmospheric temperatures due to weather or due to being up a mountain, the water will boil below its "normal" boiling point of 100 oC
What is the boiling point degrees in Fahrenheit?
At sea level the boiling temperature of water is 212o Fahrenheit. At different air pressures the boiling temperature changes. Higher air pressures require higher temperatures to boil. For example, if you go to a mountain top you could lower air pressure until water could boil at say 99o Fahrenheit. If you change substances, from water to something else, that substance would have its own individual boiling temperature, the point at which it changes from liquid to gas.
As you go to higher elevations above sea level the boiling point of water?
as you go higher above sea level, pressure decreases. Due to the decrease in pressure, the temperature needed for water to boil is less than it is than it would be at sea level. Thus, it would take less heat energy for the bonds to break and become a gas than it would in an environment with more pressure.
What effcet does altitude have on boiling point of water?
Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.
What is the melting point and boiling point of alcohol?
Wood alcohol (methanol) freezes at -97.8° C (-144.0° F) and boils at 64.7° C (148.5°F)Grain alcohol (ethanol) freezes at -114.1° C (-173.4° F) and boils at 78.5° C (173.3° F)
What has a higher boiling point alcohol or water?
Water has a higher boiling point that alcohol (ethanol). The main reason for this is because water has stronger intermolecular forces holding the molecules together.
How can one differentiate between water and alcohol with tasting or smelling it?
Boil/Freeze it. The alcohol will have a higher boiling point and lower freezing point than the water will.
What is the Boiling point of alcohol mixing with water?
The boiling point of a mixture of alcohol and water depends on the ratio of the two substances. For example, a solution of 20% alcohol and 80% water will have a boiling point higher than either pure alcohol or water. The boiling point elevation is due to the interactions between the alcohol and water molecules.
What happens when you boil alcohol?
Alcohol has a lower boiling point than water. Naturally the alcohol evaporates leaving the flavanoids and the water. If you boil 100 % alcohol, then it would act like plain water. It will boil until it all evaporates.
Why can't and alcohol thermometer be used to measure the boiling point of water?
Alcohol thermometers typically have a lower maximum temperature range compared to mercury thermometers, making them unsuitable for measuring the high boiling point of water. Alcohol thermometers may not accurately measure temperatures above their boiling point, which is lower than water's boiling point.
What effect does ethanol have on the boiling point of water?
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
Will LiCl have a higher boiling point than water?
No, LiCl (Lithium chloride) will not have a higher boiling point than water. The boiling point of water is 100 degrees Celsius, whereas the boiling point of LiCl is significantly higher at 1382 degrees Celsius.
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 alcohol solution boiling point higher or lower than salt solution?
Lower. The boiling point of ethanol is 78 degrees C. Adding salt to water raises the boiling point of that solution above 100 degrees C.
A student measures the boiling point of rainwater and sea water.Which has the higher boiling point?
Sea water has higher boiling point,as it contains sodium chloride
The normal boiling point of chloroform which has a higher vapor pressure than water at 100 degrees celsius is?
Chloroform has a normal boiling point of 61.2 degrees Celsius, which is lower than the boiling point of water. This means that chloroform will have a higher vapor pressure than water at 100 degrees Celsius, where water is at its boiling point but chloroform is not.
Which substance would have a higher boiling point sodium chloride or water?
Sodium chloride has a higher boiling point.
