Data in the table above is given for water–steam equilibria at various temperatures over the entire temperature range at which liquid water can exist. Pressure of the equilibrium is given in the second column in kPa. The third column is the heat content of each gram of the liquid phase relative to water at 0 °C.
Most computerized databases will create a table of thermodynamic values using the values from the datafile. For MgCl 2 (c,l,g) at 1 atm pressure: Thermodynamic properties table for MgCl 2 (c,l,g), from the FREED datafile. Some values have truncated significant figures for display purposes. The table format is a common way to display ...
Measurements conducted on plants predawn are considered a good representation of the total water status of plant. As no transpiration through stomata should be occurring at night, the plant's water potentials should be in equilibrium across the entire plant and be similar to the water potential of the soil around the roots.

The various triple points of water Phases in stable equilibrium Pressure Temperature liquid water, ice I h, and water vapor 611.657 Pa [8] 273.16 K (0.01 °C) liquid water, ice I h, and ice III: 209.9 MPa 251 K (−22 °C) liquid water, ice III, and ice V: 350.1 MPa −17.0 °C liquid water, ice V, and ice VI: 632.4 MPa 0.16 °C
Triple points mark conditions at which three different phases can coexist. For example, the water phase diagram has a triple point corresponding to the single temperature and pressure at which solid, liquid, and gaseous water can coexist in a stable equilibrium (273.16 K and a partial vapor pressure of 611.657 Pa).
Plant saucers are meant to keep water from dripping on your floor, but it's best to empty out your saucers after watering so your plants aren’t sitting in water for a prolonged amount of time. 4 ...
Equilibrium moisture content of wood versus humidity and temperature, according to the Hailwood-Horrobin equation. The equilibrium moisture content ( EMC ) of a hygroscopic material surrounded at least partially by air is the moisture content at which the material is neither gaining nor losing moisture.
The dependence of the water ionization on temperature and pressure has been investigated thoroughly. [5] The value of pK w decreases as temperature increases from the melting point of ice to a minimum at c. 250 °C, after which it increases up to the critical point of water c. 374 °C. It decreases with increasing pressure
