I was wondering if there is a table that shows the volume vs temperature for Mercury (Hg)?
Asked by: Zvi SzwarcAnswer
Such a table is in the CRC Handbook of Chemistry and Physics, CRC Press, Boca Raton, FL. The following is an excerpt:| °C | ml/gr |
| -10 | 0.0734205 |
| 0 | 0.073554 |
| 10 | 0.0736877 |
| 20 | 0.0738215 |
| 30 | 0.0739552 |
| 40 | 0.0740891 |
| 90 | 0.0747594 |
| 140 | 0.0754334 |
| 190 | 0.0761128 |
| 240 | 0.0767996 |
| 290 | 0.0774958 |
| 340 | 0.0782033
The following equation gives the volume accurate to about 1 part in 70,000, equivalent to 0.1 °C: V(ml./gr.) = 0.073554 + 0.000013245 * T + 1.22823*10-9 * T2 The volume (or density) versus temperature is something many of us use daily since it is the basis of mercury thermometry. You will note that the volume equation is nearly linear, as is usually assumed in Hg thermometer calibration. Answered by: Scott Wilber, President, ComScire - Quantum World Corporation |
