Good question. At sea level pressure (14.7psia), ammonia boils at -28degrees F or approximately -33degreesC. Under considerably greater pressure, it is a liquid even at room temperature. Because it can be readily compressed into a liquid at room temperature and well beyond, it becameTHE refrigerant of choice in the early days of mechanical refrigeration and air-conditioning. However, its toxic nature made it dangerous/unsuitable to use in home refrigeration, and absolutely unsuitable for use in car air conditioning. When DuPont invented dichlorodifluoromethane, or "Freon12" in the 1940s, with a P-T liquification curve similar to that of ammonia, ammonia was quickly displaced in many/most applications in favor of "Freon12" and car air conditioning came into being. However, even to this day ammonia is still used as a refrigerant in some industrial applications, such as ice houses, due to its cheap price, and it poses no threat to the overall environment.
There isn't one. The ammonia becomes less soluble in water as the temperature raises until eventually it all comes out of solution, but that's not a "boiling point" in the normal sense of the word. The boiling point of an aqueous solution of ammonia is basically the boiling point of the water modified by its colligative properties (as it would be for any other solute).
The boiling point of ammonia is −33.34 °C (which is 240 K or -28 °F).
The melting point of ammonia gas is -77.7 degrees Celsius, and the boiling point is -33.34 degrees Celsius.

Why does ammonia have a low melting and boiling point?
Ammonia has a low melting and boiling point because it has weak intermolecular forces known as hydrogen bonding between its molecules. These hydrogen bonds are easily broken, requiring less energy for the molecules to overcome and change from a solid to a liquid or gas.
Does chlorine have a high melting point low boiling point etc?
Chlorine has a low melting point of -100.98°C and a low boiling point of -34.6°C.
What change of state occurs when a substance reaches it's melting point. What occurs when it reaches it's boiling point?
When a substance reaches its melting point, it changes from solid to liquid. When a substance reaches its boiling point, it changes from liquid to gas.
Is the boiling point of something the same as the melting point?
No, the boiling point and melting point are not the same. The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid.
Why the melting point of arsenic is higher than boiling point?
The melting point of arsenic is lower than its boiling point. Arsenic has a higher boiling point than its melting point because the forces holding the atoms together in the solid state are weaker than those required to break the bonds and transition into the gaseous state.
What is the meaning of melting point of ammonia and boiling point of ammonia?
The melting point of ammonia is the temperature at which solid ammonia turns into liquid ammonia. This occurs at -77.7 degrees Celsius. The boiling point of ammonia is the temperature at which liquid ammonia turns into a gas. This happens at -33.34 degrees Celsius.
How are boiling point and melting point different?
Boiling point is the temperature point at which a liquid becomes a gas while melting point is the point at which a solid becomes a liquid.
Is the temperature at which a solid changes to a liquid the solid's boiling point?
No, it is the melting point. Ice changes to water when it melts, not when it boils.
How can you use boiling points and melting points to determine a solid liquid or gas that an element would be in at a certain temperature?
By comparing the temperature to the melting point and boiling point of the element, you can determine what state it would be in. If the temperature is below the melting point, the element would be a solid. If the temperature is between the melting and boiling points, the element would be a liquid. If the temperature is above the boiling point, the element would be a gas.
Noble gas's melting point?

Why does ammonia have a low melting and boiling point?
Ammonia has a low melting and boiling point because it has weak intermolecular forces known as hydrogen bonding between its molecules. These hydrogen bonds are easily broken, requiring less energy for the molecules to overcome and change from a solid to a liquid or gas.
Is boiling point is always same as the melting point?
No, the boiling point and the melting point are not always the same. The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid.
What is melting points and the boiling points?
Melting point: the temperature at which a solid become a liquid. Boiling point: the temperature at which a liquid become a gas.
What is the melting point and the boiling point and the normal phase for chlorine?
The melting point of chlorine is -100.98°C, the boiling point is -34.6°C, and its normal phase at room temperature is a gas.
Short difference between melting and boiling point?
Melting point is the temperature at which a substance changes from solid to liquid state, while boiling point is the temperature at which a substance changes from liquid to gas state. Melting occurs when the intermolecular forces holding solids together are overcome, whereas boiling involves the breaking of intermolecular forces within the liquid to form a gas.
