Conceptual understanding: changes in internal energy alter the pattern of particle motion to change the state of matter, or the amount of molecular motion (temperature), or contribute to a movement of charge.

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?
EMF stand for Electro Motive Force but it isn't a force. Should we investigate changing the accepted names at some point in Physics? After all, names of things can give the wrong impression.Â
