Temperatures are often measured with electrical resistance thermometers. Suppose that the resistance of such a resistance thermometer is 147 when its temperature is 23.2 °C. The wire is then immersed in a liquid, and the resistance drops to 80.1. The temperature coefficient of resistivity of the thermometer resistance is a =2.80 x 10-3 (C°)-1. What is the temperature of the liquid?
