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.

LaoAt its boiling point, water undergoes a phase change from liquid to gas, resulting in the separation of water molecules from impurities. This can make the water appear more pure, as the impurities are left behind in the liquid phase. However, the purity of the water also depends on the initial concentration of impurities present.
Boiling 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.
The 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: No it doesn't, Not even close!
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.
Not 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.

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.
What has the highest boiling point pure water or salty water?
Salty water (saltwater) has a higher boiling point than pure water, as the presence of salt in the water raises its boiling point. This is because the salt interferes with the ability of the water molecules to escape as vapor, requiring higher temperatures for boiling to occur compared to pure water.
How does pure water increase the boiling point?
Pure water increases the boiling point by forming stronger hydrogen bonds between water molecules due to the absence of impurities that can disrupt these bonds. These stronger bonds require more energy input to break, thus raising the boiling point of pure water compared to water with impurities.
Why pure water is less time to boil than water with salt?
Pure water boils faster than water with salt because adding salt elevates the boiling point of water. This means that it takes longer for the salty water to reach the higher temperature needed for boiling compared to pure water.
What is the boiling point of pure water at 4 ATM?
The boiling point of pure water at 4 ATM is approximately 125 degrees Celsius.
