N 0 further calibration for the temperature interval 0 to 650° C. Is required because practically all available data indicate that all resistance thermometers define nearly the same scale and that temperatures calculated by the formula given do not differ from those determined with the gas thermometer by more than the experimental errors.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
