Vapour pressure of water vs temperature
Liquid water from 0 to 100 °C at 1 atm — density, viscosity, specific heat, thermal conductivity and vapour pressure, all at the same state.
Vapour pressure in kPa, from 0 to 100 °C. The chart and the table below are the same numbers; the table is the one you can copy.
