1. The problem statement, all variables and given/known data What is the formula that allows you to find the temperature of any given thermometer that varies its temperature with some property? For example is a pressure of 10mmHg means 0degC, what would the pressure be at 50degC? 2. Relevant equations This is what I'm looking for. I used to know the equation but I've completely forgotten. 3. The attempt at a solution I don't want the answer to my question, just the formula.
