Chemistry - States of Matter - Revised
CertificationView course modules
A state of matter is one of the distinct forms in which matter can exist. This course will discuss the four observable states of matter in everyday life which are solid, liquid, gas, and plasma. You will learn that plasma is the most common state of matter in the universe. You will then learn that latent heat is the heat required to convert a solid into a liquid or vapor, or a liquid into a vapor without change of temperature.
Vaporization is the heat needed to change the state of a substance from liquid to gas, while fusion is the heat needed to change the state of a substance from solid to liquid. This course will teach you how to calculate the change in energy needed to change the state of matter. You will learn how to read phase and phase change diagrams as well as look into a chilling water problem to better understand the state of matter phase change.
All things are made up of matter, so by studying the properties of matter and learning their different physical characteristics you can understand the world around you a little bit better. This course give you that little bit of interesting knowledge in a clear manner. So, check out this course and learn what happens when matter changes from solid to liquid to gas in just a few short hours!
Having completed this course you will be able to:
- List the four states of matter
- Describe the relationship between state and energy
- Analyse phase change diagrams
- Calculate the change in energy needed to change state
- Discuss how to apply the above to water molecules
