Learning Paths
Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
Chapter 5Contains Standard content
Systems, Work, Heat and the First Law, Enthalpy and Hess's Law, Entropy, Gibbs Energy and Spontaneity
Why does a hot cup of tea cool down but never warm itself up? Why does ice melt in a warm room but not in a freezer? Thermodynamics answers questions like these with a few precise laws about energy. In this chapter you meet systems, work and heat, measure enthalpy changes, add them with Hess's law, and use entropy and Gibbs energy to decide whether a reaction can happen on its own. Python adds up the energy changes for you.
