Boiling point is at -28° F.
Freezing point is at -107.9° F; a white crystalline mass forms.
Critical temperature is at 270.3° F; ammonia exists as a vapor, regardless of pressure above this temperature.

What is the meaning of melting point of ammonia and boiling point of ammonia?
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
What are the melting point and boiling point of Ammonium?
If you mean ammonia, the melting point of ammonia is −77.73 °C, and its boiling point is −33.34 °C. (Wikipedia)
Melting point of Ammonia?
I know the freezing point, it's 77.73
What is the boiling point of ammonium?
The boiling point of ammonia at atmospheric pressure is -33.34oC.
Why does ammonia have a high boiling point?
Hydrogen bonding

How is ammonia used as refrigerant?
Ammonia has a low boiling point, is cheap, largely available and energy efficient.

Does ammonia have a higher boiling point than methane?
Yes, Boiling point of ammonia, NH3: - 33,34 0C Boiling poit of methane, CH4: - 161,6 0C
What Is the flash point of ammonia?
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
When ammonia reaches its freezing point what will happen?
It forms a white crystalline mass. Ammonia freezes at -107 degrees C.
What is the boling point of ammonia?
-33 at atmospheric pressure 103kpa
Why water has more boiling point than ammonia and hydroflouric?
Water is a liquid at room temperature; ammonia and hydrofluoric acid are gases.
Which Ammonia is A good grade Refrigerant?
There are not different "types" of ammonia. Ammonia is a gas and when you buy ammonia usually it is absorbed in water at different strengths. You may see ammonia sold as ".88" liquid for instance. The ammonia is used in conjunction with water and hydrogen in an ammonia cycle refrigeration plant. The ammonia/hydrogen is released into the evaporator (cold side) of the fridge. The ammonia boils off to a gas (boiling point of ammonia, in open atmosphere, is -33 oC -the pressure in system keeps it liquid). The Hydrogen/ammonia gasses leave the evaporator and are separated by absorbing the ammonia in water. The hydrogen rises back to the top of the system and the ammonia solution falls to the bottom. The only thing left to do is separate the ammonia and water by heating it (distillation) so that the cycle can be repeated. The purpose of the hydrogen the system is to control the boiling point (vapour pressure) of the ammonia.
