The resistance of a platinum resistance thermometer is 125 ohms when its temperature is 20.0 degrees Celsius. The wire is then immersed in boiling chlorine, and the resistance drops to 99.6 ohms. The temperature coefficient of resistivity of platinum is 3.72 x 10^-3 (Celsius^-1). What is the temperature of the boiling chlorine?
