A thermometer is removed from a beaker of boiling water and placed in a beaker of room temperature water. The thermometer takes 15 seconds to reach a reading of 25°C. The same thermometer is returned to the boiling water for several minutes. It is then placed under a tap of running water at room temperature.The thermometer takes only 10 seconds to reach a reading of 25°C.
