The length of the column of mercury in a thermometer is 3.3 cm when the thermometer is immersed in ice water at 1 atm of pressure and 23.3 cm when the thermometer is immersed in boiling water at 1 atm of pressure. Assume that the length of the mercury column varies linearly with temperature. (a) Sketch a graph of the length of the mercury column versus temperature (in degrees Celsius). (Do this on paper. Your instructor may ask you to turn in this work.) (b) What is the length of the column at room temperature (22.0°C)? X cm (c) If the mercury column is 24.7 cm long when the thermometer is immersed in a chemical solution, what is the temperature of the solution? °C
