A new virial equation of state for ammonia was obtained. The second and the third coefficients of the equation were determined, using the experimental results of Beattie and Meyers, and the values that were calculated with the molecular theory by Rowlinson were adopted as the second virial coefficient for low temperature. A formula for specific heat of vapour ammonia under the ideal state was obtained, using the values that were calculated by Harrison and Kobe. A formula of vapour pressure of ammonia was obtained for a temperature range from -70°C to the critical temperature, using the experimental results of Cragoe and the others. The other charactaristic equations were made through thermodynamical calculation. The author calculated the charactaristic values of ammonia from the equation of state and the others, and made i-log10P diagram for a temperature range from 0.2kg/cm2 to 80kg/cm2 and also for a temperature range from -60°C to 300°C.
