    Reason why Mercury is preferred to alcohol as thermometric liquids. 1. Mercury has a much greater conductivity than alcohol and expands rapidly, and thus indicates a temperature change quickly ... Mercury does not wet glass but alcohol because of its concave meniscus tends to cling to the walls of stem of the thermometer.
