134 K, highest-temperature superconductor at ambient pressure, mercury barium calcium copper oxide; 165 K, glass point of supercooled water; 184.0 K (–89.2 °C), coldest air recorded on Earth; 192 K, Debye temperature of ice; 273.15 K (0 °C), melting point of bound water; 273.16 K (0.01 °C), temperature of triple point of water; c. 293 K ...
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.
δ 18 O, a proxy for temperature, for the last 600,000 years (an average from several deep sea sediment carbonate samples) [a]. The 100,000-year problem (also 100 ky problem or 100 ka problem) of the Milankovitch theory of orbital forcing refers to a discrepancy between the reconstructed geologic temperature record and the reconstructed amount of incoming solar radiation, or insolation over ...
A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%). B Calculated values *Derived data by calculation.
A 1960 report on the Nevada granite (Izett, USGS) is posted on the internet but the very small numbers there are hard to understand. [81] Robertson says that Rockport-1 has 25% Quartz and Rockport-2 has 33% Quartz and he usually talks in volume percent. Robertson page 35.

The best part of the science fair, Recio said, is testing out experiments. Third grade student William Kim admires a winning science fair project on ants at Miller High School on Friday, Jan. 19 ...
The difference of temperatures between the freezing- and boiling-points of water under standard atmospheric pressure shall be called 100 degrees. (The same increment as the Celsius scale) Thomson's best estimates at the time were that the temperature of freezing water was 273.7 K and the temperature of boiling water was 373.7 K. [33]
