1-9 The length of the mercury column in a certain mercury-in-glass thermometer is 5.00 cm when the thermometer is in contact with water at its triple point. Consider the length of the mercury column as the thermometric property X and let 0 be the empirical temperature determined by this thermometer. (a) Calculate the empirical temperature, measured when the length of the mercury column is 6.00 cm. (b) Calculate the length of the mercury column at the steam point. (c) If X can be measured with a precision of 0.01 cm, can this thermometer be used to distinguish between the ice point and the triple point?
