THE THERMOELECTRIC EMF OF MERCURY RELATIVE TO PLATINUM.
Abstract
It has been suggested that published values for the thermal emf of mercury relative to platinum were incorrect and hitherto no values were available at temperatures below 0 deg. C. Equipment was designed and calibrations made in the range -35 to +200C reproducible to +0.5 or -0.5 deg C. Above 0 deg. C results are about an order lower than published values. Below 0 deg. C two reversals of polarity occur whilst at the freezing point (-38.87C) there is a sudden inversion of the rate of change of emf with temperature. Reproducibility below this point was found to be not better than +2 or -2 deg. C. (Author)
