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.
Because of its hydrogen bonding.
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 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.
Phenylmagnesium bromide does not have a melting point. It is soluble in diethyl ether and THF and has a flash point of -45 degrees C.
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
