Critical Temperatures and Pressures for some common substances. It is equal to a pressure of 133.3224 pascals or 0.00131579 atmospheres. This is the basis of the Kelvin scale and it is equal to 0.01 о C, which is the freezing point of water. Two geometrical configurations of the sample are compared and the effect of impurities considered. While using this site, you agree to have read and accepted our Terms of Service and Privacy Policy. The triple point of pure water is at 0.01 degrees Celsius and 4.58 millimeters of mercury and is used to calibrate thermometers. The pressure dependence of the melting point, using small samples, was found to be 4.8 + 0.2 mK bar- 1, corresponding to a difference of 4.8 mK between the normal 190 E. M ~ndez-Lan9o, J. Ancsin/Thermochimica Acta 287 (1996) 183-190 melting and triple points. American Heritage® … Google use cookies for serving our ads and handling visitor statistics.

Sometimes only the term triple point is used, which refers to both the temperature and the pressure at which the three phases co-exist in equilibrium. Triple point for some common substances: See also Critical Temperatures and Pressures for some common substances 1 kPa (103 Pa) = 0.145 psi The triple point is not the same as the critical point. Millimeters of mercury is a non-SI unit of Pressure. A millimetre of mercury is a manometric unit of pressure, formerly defined as the extra pressure generated by a column of mercury one millimetre high, and currently defined as exactly 133.322 387 415 pascals.

The triple point of water is 273.16 K at 611.73 Pa. Please read AddThis Privacy for more information. 1 mmHg is also equal to 1 Torr. The triple point and melting point of mercury were studied by continuous melting and adiabatic calorimetry techniques. Although not an SI unit, the millimetre of mercury is still routinely used in medicine, meteorology, aviation, and many other scientific fields. Select a conversion type and the desired units. Triple point:  The combination of the temperature and the pressure at which the three phases (gas, liquid, and solid) of a substance coexist in thermodynamic equilibrium.
