Introducing Enthalpy Change and Enthalpy level diagrams

2 complete lessons introducing enthalpy changes. By the end of the lesson students should:
Know that enthalpy is the heat change measured at a constant pressure and state the standard conditions
Be able to define what we mean by standard enthalpy of a reaction
Be able to construct and interpret enthalpy level diagrams showing an energy change

Lesson includes discussion points and questions to check understanding.
