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 chemistry course about states of matter 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.
This chemistry course will be of great interest to all students who wish to pursue a career in any of the sciences such as chemistry, physics, biology or geology, or the individual learner who simply wants to learn and understand what is happening when matter changes from solid to liquid to gas.
Learning outcomes: - Learn about the four states of matter; - Understand the relationship between state and energy; - See how to read phase and phase change diagrams; - Learn how to calculate the change in energy needed to change state; - See how to apply the above to water;
