A previous answer stated 36° C
This is obviously not correct as coffee (the drink) is not solid at room temperature. Nor do coffee beans or grounds melt at this temperature which would not be extreme for the natural environments in which coffee crops are traditionally cultivated.
As coffee when prepared for drinking is primarily water, the melting point is probably similar to that of water, i.e. ~0° C.
Impurities in water normally have the effect of lowering the melting point, which means that the melting point of coffee is likely to be just below that of water.
The exact value would differ from cup to cup depending upon the beans used and the concentration or strength. The addition of sugar and/or dairy products would also be factors affecting the melting point.

∙ 14y agoBoiling point of water is higher (100C) as opposed to 78C for alcohol This is due to the fact that the dipole between the methyl groups in alcohol are lower and thus the hydrogen bonds holding them together are more easily broken. In water however, as a result of the high electronegativity of oxygen STRONG hydrogen bonds are formed and therefore require more energy (heat) to be broken.

∙ 12y agoThe boiling point of coffee in drink form will be a bit greater than the boiling point of water, which is 100 degrees Celsius at sea level.
This is affected by the atmospheric pressure at the observed location and the concentrations of coffee and sugar.
If you were on top of a mountain, it would be considerably lower.

ANSWER: actually, coffee can boil. (i know that from experience!) I'm not sure what temperature though
Because coffee is loaded with solutes, it will not boil at the same temperature as water. Adding any solutes to water will raise the boiling point of the resulting mixture. The stronger the coffee, the higher the boiling point. Since the exact strength of the coffee can vary so much it is impossible to specify an exact boiling point for it - but it WILL be higher than that of pure water.

∙ 9y agoNot necessarily. If the pressure is one atmosphere, and the watery fluid starts to boil at the boiling point of water (100 deg C), then it is very likely to be pure water.
Solutes will raise the boiling point, lowered pressure will lower the boiling point. So it is possible to lower the pressure to lower the boiling point but add a solute to raise the boiling point to exactly offset that.

∙ 12y agoCoffee beans don't boil !
Only coffee as drink (solution/suspension in water) can boil at a temperature greater, but not so much, than
100 0C (this depends on the coffee, sugar and other additives concentrations).

How does pure water increase the boiling point?
Pure water does not increase - or in any other way affect - the boiling teperature of water becasue the latter is normally taken to be that for pure water!The question does not make sense. What type of water is it whose boiling temperature is meant to be increased by pure water? Impure water?In any case, pure water does not increase the boiling point of water but lowers it.
What are the boiling and melting point's of salty water?
That depends on how much salt is dissolved in the water. Generally, the boiling point will be higher than for pure water, and the melting point will be lower than for pure water.
Why pure water is less time to boil than water with salt?
The boiling point of pure water is lower than the boiling point of a water-salt solution, so it takes takes longer to heat the water-salt solution to its boiling point.
What has the highest boiling point pure water or salty water?
Salty water.
Will it take longer to boil salt water than fresh water?
Yes. The boiling point of salt water is higher than the boiling point of pure water.
How can boiling point be used to find out if a substance is pure?
At Boiling Point all the material evaporates leaving no residue which means it is pure. But if it leaves some residue after evaporating at boiling point then it is not pure. For example : If you take an example of pure water & Saline Water then pure water will evaporate at its boiling point leaving nothing after it. But Saline water evaporates leaves salt behind it.

The boiling point of pure water is?
The boiling point of pure water is typically about 100 degrees Celsius. This value can vary based on factors such as pressure. Additionally, impurities in a sample of water can alter its boiling point.
What are the boiling and melting point's of salty water?
That depends on how much salt is dissolved in the water. Generally, the boiling point will be higher than for pure water, and the melting point will be lower than for pure water.
Why pure water is less time to boil than water with salt?

How does the boiling point of water change when it is not pure?
It increases.
What has the highest boiling point pure water or salty water?
Salty water.
What are the procedures for fresh water evaporates faster than salt water?
The boiling point of pure water is lower than the boiling point of salt water.
What is the affect of the boiling point when you add salt in pure water?
It raises the boiling point of water and it can make it taste funny and yooh smell
What is the average for the water boiling point?
Pure water boils at 100oC (212oF)
Boiling point of water at sea level in Fahrenheit?
212F for pure water.
Will it take longer to boil salt water than fresh water?
Yes. The boiling point of salt water is higher than the boiling point of pure water.
