Resistance thermometer . 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 platnum resistance thermometer is `164.2 Omega ` When praised in a particular solution, the resistance is`187.4 Omega ` . What is the temperature of this solution ?

To solve the problem of finding the temperature of the solution using a platinum resistance thermometer, we can follow these steps: ### Step 1: Understand the relationship between resistance and temperature The resistance of a conductor changes with temperature. For a platinum resistance thermometer, the relationship can be expressed as: \[ R = R_0 (1 + \alpha (T - T_0)) \] where: ...
