In this lesson, we are going to define pressure and explain some of the units that are used to express measurements of pressure. Have you ever wondered what the lowest possible temperature is? In this lesson, you will learn what temperature measures. You will also be introduced to the Kelvin scale an absolute scale and learn how it relates to the Celsius scale.

The density of gas is more complicated than solids because gases are highly affected by temperature and pressure.

This lesson will lead you through two equations to calculate the density of a gas. You will also learn how to use this information to explain how to find the partial pressure of a gas collected over water. Gas particles are always moving around at random speeds and in random directions.

This makes it difficult to determine what any one particle is doing at a given time. Luckily, the Maxwell-Boltzmann distribution provides some help with this. Have you ever been in a room where someone has put on perfume or scented lotion and a few minutes later you are able to smell it?

What causes you to be able to smell something from so far away? In this lesson, we are going to use the kinetic molecular theory of gases to explain some of their behaviors and determine how we can compare the speeds of different gases.

Have you ever wondered why a balloon expands when you blow it up? How something as light as air is able to exert a force large enough to inflate a balloon? In this lesson, you will learn about the relationship between the volume of a container filled with a gas and the number of gas particles that container holds.

Have you ever wondered how an air powered water gun works? It uses the fantastic properties of gases to make a summer day more enjoyable! In this lesson, we are going to discuss the law that governs ideal gases and is used to predict the behavior of real gases: The ideal gas law is used to describe the behavior of ideal gases, but sometimes the conditions are such that gases behave differently.

When this is the case we can use the van der Waals equation to describe the behavior of real gases under these non-ideal conditions. To understand real gas behavior we use the van der Waals equation. This allows us to account for the volume and attractive forces of gas molecules. Can you think of a measuring device that is just as reliable as the forecast provided by your local meteorologist?

Use this lesson to learn about this device, called the barometer. Find out the history behind its discovery and how it functions.
