Question

At the temperature does solid ice and liquid water co- exist together?

Answer 1

The single combination of pressure and temperature at which liquid water , solid ice and water vapor can co exist in a stable equilibrium occurs at exactly 273.16 K ( 0.01 degree C ; 32.02 degree F) and a partial vapor pressure of 611.657 pascals (6.11657 mbar 0.00603659 atm).

Answer 2

The single combination of pressure and temperature at which liquid water , solid ice and water vapor can co exist in a stable equilibrium occurs at exactly 273.16 K ( 0.01 degree C ; 32.02 degree F) and a partial vapor pressure of 611.657 pascals (6.11657 mbar 0.00603659 atm)

Rememver 273K = 0 C.
