Module 3—Behaviour of Gases

Lesson Summary

In this lesson you investigated the following questions:

• What is the Kelvin temperature scale, and why is it used?
  
  
• What are the relationships among amount, pressure, volume, and temperature for a fixed amount of gas?

In this lesson you explored the Kelvin temperature scale and the basis of this scale—absolute zero. You discovered that when using Charles’ law and the combined gas law, Kelvin temperatures are needed. As such, you converted between degrees Celsius and kelvin.

You then discovered Charles’ law, which states as the temperature of a gas increases, the volume increases proportionally, provided that the pressure and chemical amount of gas remain constant.

You performed calculations and completed a virtual lab based on Charles’ law.

Finally, you combined Charles’ law with Boyle’s law to form the combined gas law and performed various calculations based on the resulting formula.
