# At what temperature and pressure is ammonia liquid?

## At what temperature and pressure is ammonia liquid?

of liquid ammonia at saturation pressure. At atmospheric pressure, ammonia, NH3, is present as a liquid at temperatures below -33.6 °C (-28.5 °F). At 10 bara, the condensation/boiling point is 25 °C (77 °F). For more details about phase transitions, see ammonia phase diagram.

## What is the temperature of ammonia?

Anhydrous ammonia boils at -28°F and freezes to a white crystalline mass at -108°F. When heated above its critical temperature of 270.3°F, ammonia exists only as a vapor regardless of the pressure. Between the melting and critical points, liquid ammonia exerts a vapor pressure, which increases with rising temperature.

At what temperature does ammonia boil?

-28.01°F (-33.34°C)Ammonia / Boiling point

At what pressure does ammonia boil?

597 at 32°F. At atmospheric pressure, NH3 boils at -28°F. As the temperature rises, the vapor pressure increases rapidly….Anhydrous Ammonia Basics.

### What is the partial pressure of ammonia?

The partial pressure of ammonia is 1.82 atm.

### At what temperature does ammonia dissociate?

As is evident in the inset of Figure 1, the desorption temperature of ammonia (360 K) is comparable to the temperature for its activated dissociation (300-410 K), therefore it is reasonable to assume that desorption of ammonia and dissociation are very competitive.

At what temperature does ammonia freeze?

-107.9°F (-77.73°C)Ammonia / Melting point

What is the saturation temperature of ammonia?

-33.6°C.
Saturation temperature: The saturation temperature is the temperature for a corresponding saturation pressure at which a liquid boils into its vapor phase. At atmospheric pressure, the saturation temperature of the ammonia is -33.6°C.

## What state is ammonia at room temperature?

gas
At room temperature, ammonia is a colorless, highly irritating gas with a pungent, suffocating odor. In pure form, it is known as anhydrous ammonia and is hygroscopic (readily absorbs moisture).
