Surface Tension Data: water
Surface tension of liquids vs. temperature (liquid-air interface) in mN/m, with temperature coefficients and contact angles. Covers water (IAPWS 2014, 0-200 C), common solvents (ethanol, methanol, acetone, benzene, toluene, hexane, octane, dodecane, glycerol, ethylene glycol), cryogens (liquid N2, O2), refrigerant R-134a, acids, alkalis, molten metals (solder, aluminum, steel), and mercury.
| substance | temperature C | contact angle on glass deg (deg) | phase pair | surface tension mN per m (mN/m) | temperature coefficient mN per m per C (mN/m/C) |
|---|---|---|---|---|---|
| water | 5 | 0 | liquid-air | 74.89 | -0.1514 |
| water | 10 | 0 | liquid-air | 74.23 | -0.1514 |
