  • Ammonia - Specific Heat at varying Temperature and Pressure

    Isochoric specific heat (Cv) is used for ammonia in a constant-volume, (= isovolumetric or isometric) closed system. At ambient pressure and temperature the isobaric specific heat, C P, of ammonia is 2.2 [kJ/kg K] or 0.52 [Btu/lb °F] = [cal/g K], while the isochoric specific heat, C V, is 1.6 [kJ/kg K] or 0.39 [Btu/lb °F] = [cal/g K].

    Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests an alkali with composition [NH 4 +][OH −], it is actually impossible to isolate samples of NH 4 OH.
