Thermal physics covers macroscopic (whole systems) and microscopic (particles) processes.

During this topic you will be develop a better understanding of the following questions and more:

  • What is the evidence that everything is made of atoms?
  • What is the difference between heat and temperature?
  • What is the relationship between heat added and temperature increase?
  • Why doesn´t the temperature of water change when it boils?
  • What are the gas laws?
  • How do you use a P-V diagram?
  • Where does the energy go when work is done against friction?

  • Thermal concepts

    To understand what happens to the energy we transfer to a body when we do work against friction we need to look inside the body. Having studied mechanics, which is basically the physics of a small ball, you will be ready to apply what you know the the smal

  • Modelling gases

    Because there are no forces between gas molecules, the gaseous state is the simplest to model. We will start by considering the molecules but then look at the bigger picture of the relationship between pressure volume and temperature.
