Chemistry - Gases and Their Properties
Gases behave differently from either solids or liquids, so there are different methods for understanding their behaviour. Having neither fixed volume nor shape gases are moulded entirely by the container in which they are held and from this it is possible to measure their behaviour by measuring properties such as pressure, volume, temperature and number of molecules.
To qualify for your official ALISON Diploma, Certificate or PDF you must study and complete all modules and score 80% or more in each of the course assessments. A link to your Diploma certificate will then appear under the My Certificates heading of your My Account page.
Learning outcomes: - Understand how gases behave under pressure; - Recognise the characteristics of an Ideal gas; - Learn how to calculate the pressure of a gas filled container; - See how changes to pressure, temperature or volume affect each other; - Learn how solve for any part of the Ideal Gas Equation; - Understand the core units of measure for temperature.

|Course Description|| Gases behave differently from either solids or liquids, so there are different methods for understanding their behaviour. Having neither fixed volume nor shape gases are moulded entirely by the container in which they are held and from this it is possible to measure their behaviour by measuring properties such as pressure, volume, temperature and number of molecules. This free online chemistry course will introduce the concept of the ideal gas and the ideal gas law which is a good indicator of the behaviour of gases under many different conditions. The various components in the ideal gas law are explained in clear terms and you will see that by using equations you will understand how the impact of a change to one property, for example temperature, will impact on the other properties. Where there are multiple gases in a container you will be shown how to work out their partial pressure relative to the total pressure. This free online 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, and to the individual learner who simply wants to learn and understand how gases behave.
