# Ch 11: Gases & Gas Laws

Watch video lessons and learn about the properties and scientific laws associated with gases. These video lessons are short and engaging and make learning easy!

## Gases and Gas Laws - Chapter Summary and Learning Objectives

Gases, such as the atmospheric layer that encircles the earth, are dispersed and random groups of atoms that are typically colorless and invisible to the naked eye. In this chapter, you'll learn about the scientific theories used to explain how and why gas particles move, as well as how to measure the physical properties of gases. You'll also find out how a change in a gas property, like temperature or volume, can affect calculations for the other variables.

As all gases have to follow the rules, just like students, the instructor will discuss the four components that make up the ideal gas law. You can also find out what happens to gases in less than ideal environments and how to use an equation to describe these situations. When you've finished watching the videos and completing the self-assessment quizzes, you should be able to:

• Identify the properties of ideal gases
• Define units of measurement and make calculations for gas pressure, quantity, temperature and volume
• Explain gas behaviors and why some move faster than others
• Identify the four components of the ideal gas law, including number of moles, pressure, temperature and volume
• Understand the relationships that exist among gas properties, such as pressure and volume
• Use scientific law to predict the behaviors of real gases.

VideoObjective

Pressure: Definition, Units and Conversions Identify and convert among the units of measurement for gas pressure.
Temperature Units: Converting Between Kelvins and Celsius Define temperature, and convert between Celsius and Kelvins scales.
Density of Gas Explain how to calculate the density of a gas.
Dalton's Law of Partial Pressures: Calculating Partial and Total Pressures Determine partial and total pressures using Dalton's Law, and discuss how to find the partial pressure of a gas assembled over water.
The Boltzmann Distribution: Temperature and Kinetic Energy of Gases Describe the relationship between gas temperature and average kinetic energy.
Diffusion and Effusion: Graham's Law Compare the relative velocities of gases by means of their molecular masses.
Molar Volume: Using Avogadro's Law to Calculate the Quantity or Volume of a Gas Find the quantity or volume of a gas at standard temperature and pressure.
Boyle's Law: Gas Pressure and Volume Relationship Predict how a change in volume or pressure affects the other variable using Boyle's Law.
Charles' Law: Gas Volume and Temperature Relationship Use Charles' Law to calculate how a change in temperature and volume affects the other variable.
