    Calculate the temperature measured on the resistance scale

    I've corrected the values of alpha and beta, does it make more sence now? I've been told that this question has all the information you need to solve it. Can anyone help? Thanks, rob.

    Calculate the temperature measured on the resistance scale

    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...

    Mercury thermometer temperature problem

    Hi, Yes, in the question it didn't actually mention the temperature, just that it was the triple point. Its supposed to be a pretty basic thermal physics question, any ideas what formula I would need to use? Thanks, rob.

    Mercury thermometer temperature problem

    The length of the mercury coloumn in a mercury thermometer is 5cm when the bulb is immersed in water at the triple point (273.16k). What is the temperature if it reads 6.0cm? What will the length of coloum be if immersed in boiling water (at steam point)? I'm new to this forum, but would...
