Step 1: Identify the known values and the formula for an uncalibrated thermometer. The length of the mercury thread at 0^ (melting ice) is L_0 = 18 mm. The length of the mercury thread at 100^ (steam) is L_100 = 138 mm. The length of the mercury thread in the hot liquid is L_T = 118 mm. The temperature T on a linear scale can be found using the formula: T = (L_T - L_0)/(L_100) - L_0
