Answer:
Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation.
Solid state: Ice
Boiling point: 99.98 °C (373.13 K)
Heat of vaporization: 2.27 MJ/kg
Specific gas constant: 461.5 J/(kg·K)
