TOK questions associated with this unit:
Temperature is a quantity that we can perceive and measure, why isn't feeling good enough to base a physical model on?
Temperature is a quantity that cannot be measured directly, we have to use e.g. the length of a mercury column. Can we really say that we are measuring temperature?
Why is red used to show higher temperatures when blue makes more sense?
