Density of Ammonia. (c) critical point pressure of ammonia, in kPa? DESCRIPTION (Ammonia): At room temperature and atmospheric pressure, ammonia is a colorless, alkaline gas having a pungent odor. These species exploit high solar irradiance in the alpine zone to warm the leaf canopy to >25 C on sunny days, but they must also tolerate low, often subzero, growth temperatures during cloudy days and at night. T c: Critical temperature: T fus: Fusion (melting) point . Thus propane in a high-pressure cylinder consists of a mixture of liquid and vapor, and you can sometimes hear the liquid sloshing about inside. pH: Ammonia concentration and toxicity increases as pH increases, although less ammonia is required to produce toxic effects at lower pH (IPCS 1986, Wurts 2003). For example, the Celsius scale (symbolized by C and spoken as "degrees Celsius") defines 0C as the freezing point of water and 100 C as the boiling point of water. . The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied.
