Calculate the temperature measured on the resistance scale

[robgb]

Thermal physics question...

A wire resistance thermometer is constructed with material that has a resistance that varies as temperature as below.

R=R0 (1+ alphaT + betaT^2)
where constants alpha and beta are 3.8 x 10^-3 k^-1 and -3.0 x 10^-6 k^-2 respectively.

Calculate the temperature measured on the resistance scale at 70 degrees C on the ideal gas scale.

I've got no idea where to start on this one, any ideas?

Thanks, Rob.

I've corrected the values of alpha and beta, does it make more sense now?

I've been told that this question has all the information you need to solve it.

Can anyone help?

Thanks, rob.
