Flash point for ammonia is the point where it becomes flammable after a phase change from a liquid to gas forming a flammable mixture in air. Obviously this is different to the lowest flammable concentration in air. In the case of ammonia it is 11 degrees according to the MSDS: http://msds.chem.ox.ac.uk/AM/ammonia_anhydrous.html
It forms a white crystalline mass. Ammonia freezes at -107 degrees C.
The melting point of a substance is based upon the polarity of the bonds that make up the substance. In water, the O-H bond has a difference in electronegativity of 1.4 (Pauling's Scale) and in ammonia, the N-H bond has a difference in electronegativity of .9. Therefore, it takes more energy to break apart the O-H bond because the polarity is so great, and this is why it has a higher melting point than ammonia.
Ammonia has an unusually high boiling point compared to other molecules of similar size because it forms strong hydrogen bonds, which require more energy to break. These hydrogen bonds create a network of intermolecular forces that hold the ammonia molecules together, resulting in a higher boiling point.
Household ammonia, which is typically a solution of ammonia gas dissolved in water, freezes at approximately -77.7 degrees Celsius or -107.8 degrees Fahrenheit. Ammonia is a compound with a lower freezing point compared to pure water, which freezes at 0 degrees Celsius or 32 degrees Fahrenheit. It is important to note that the freezing point may vary slightly depending on the concentration of ammonia in the solution.
Ammonia is a compound of Hydrogen and Nitrogen(NH3). It is normally found as a stinky, lighter than air, gas.Therefore at 'room temperature' it melting point is approximately -77C, and its boiling point -33C. Its low density and atomic weight set its phase change points.
The meaning is at what temperature does ammonia melt at and what temperature does ammonia boil at? for eg. waters melting point is 0 degrees celcius and the boiling point of water is 100 degrees celsius
