Would ammonia be a solid, liquid or gas at
a) - 55 °C
b) - 17 °C
c) - 113 °C
Let's start by taking a close look at ammonias boiling- and melting points
boiling point is the temperature
at which the compound changes
from liquid to gas
boiling point of NH3 = - 33.34 °C
phase change of ammonia
melting point is the temperature
at which the compound changes
from solid to liquid
melting point of NH3 = - 77.73 °C
