Thermodynamics resistance temperature scale

  1. Sep 19, 2015 #1
    1. The problem statement, all variables and given/known data

    IMPORTANT:There is an error in the statement.α and β are in C not K

    2. Relevant equations

    R=Ro(1 +αt+βt2)
    3. The attempt at a solution
    I really don't know what to do because if I isolate t in the equation it will give me the temperature on the ideal gas scale whereas the temperature I need to find is on the resistance scale.

    Re-read the problem statement: where is "K" used? What does the "correction" imply should be used instead?

    The temperature is in celsius degrees not kelvin so the constant α is in celcius^-1 and β in celcius^-2 in order to negate t and t^2. This is a correction our teacher made after giving us the statement. Is that what you were reffering to?

    Are you saying I simply need to solve R for the given conditions? Because that would give me a value of resistance not temperature and the exersice is to find the ideal gas temperature equivalent on the resistance scale.
