Gases objectives

We are just starting the Gases unit. Here are the big picture questions that I would like you to keep in mind while we’re working through this unit:

  • Why are certain gases better suited for specific uses?
  • How can you handle gases safely?
  • What is the difference between a real gas and an ideal gas?

In addition, here is a summary of what you are responsible for in this unit:
