The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in ... 1 January 1895). "Melting Points of Aluminum, Silver, Gold, Copper, and ...
[8] [11] Wedgwood tried to compare his scale with other scales by measuring the expansion of silver as a function of temperature. He also determined the melting points of three metals, namely copper (27 °W or 4,587.5 °F (2,530.8 °C)), silver (28 °W or 4,717.5 °F (2,603.1 °C)) and gold (32 °W or 5,237.5 °F (2,891.9 °C)). All these ...

In more specialized fields of study and applications the number of elements counted as noble metals can be smaller or larger. It is sometimes used for the three metals copper, silver, and gold which have filled d-bands, while it is often used mainly for silver and gold when discussing surface-enhanced Raman spectroscopy involving metal ...

For example, both the old Celsius scale and Fahrenheit scale were originally based on the linear expansion of a narrow mercury column within a limited range of temperature, [4] each using different reference points and scale increments. Different empirical scales may not be compatible with each other, except for small regions of temperature ...
Historically, on the Fahrenheit scale the freezing point of water was 32 °F, and the boiling point was 212 °F (at standard atmospheric pressure). This put the boiling and freezing points of water 180 degrees apart. [8] Therefore, a degree on the Fahrenheit scale was 1 ⁄ 180 of the interval between the freezing point and the boiling point ...
Melting points (in blue) and boiling points (in pink) of the first eight carboxylic acids (°C). For most substances, melting and freezing points are approximately equal. For example, the melting and freezing points of mercury is 234.32 kelvins (−38.83 °C; −37.89 °F). [2]
