Chemistry – States of Matter

Course Level 2: Intermediate

Estimated Study Time: 1-2 hours

Matter exists in four states – solid, liquid, gas and plasma and it will change state depending on the temperature and pressure applied to the matter. In this course you will learn about the characteristics of each of the four states and the amount of energy that can be added to or taken from a substance before it starts to change state.

As all substances change state at different temperatures and pressures you will learn how to use phase change diagrams to plot the energy and pressure levels, the triple point, critical temperature, boiling and melting points associated with different substances. You will also learn in a step by step manner how to calculate the change in energy needed to move a substance along the state of matter spectrum.
