Physical Chemistry #13: The Liquid State, Phase Changes and Vapour Pressure (Slides and Tasks)

In this lesson we discuss the liquid state, phase changes and the concept of vapour pressure. This is lesson thirteen in our physical chemistry series for Unit 4: States of Matter (from the Cambridge International AS Chemistry Curriculum (9701) 2019-2021 curriculum).

LESSON OBJECTIVE: Understand the liquid state using the kinetic model and describe how particles behave during phase changes and at vapour pressure.

Learning Outcomes (from the Cambridge AS Chemistry Curriculum 2019-2021):
4.2 The liquid state
a) describe, using a kinetic-molecular model, the liquid state, melting, vaporisation and vapour pressure.
