Problem (3) The variation in electrical resistance with temperature can be used to make precise temperature measurements. Platinum is commonly used since it is relatively free from corrosive effects and has a high melting point. Suppose at 20.0°C the resistance of a platinum resistance thermometer is 164.212. When placed in a particular solution, the resistance is 187.422. What is the temperature of this solution? The temperature coefficient of resistivity for platinum is 3.927 x 10-3 (Cº)-1.
