At standard pressure, ammonia melts at 195 K and boils at 240 K. If a sample of ammonia at standard pressure is cooled from 200 K down to absolute zero, what physical constants are needed to calculate the change in
enhtalpy?
I) the heat capacity of ammonia(s)
II) the heat capacity of ammonia(`)
III) the heat capacity of ammonia(g)
IV) the enthalpy of fusion of ammonia
V) the enthalpy of vaporization of ammonia
