Task Description

Standards

In this task students will use the simulation to distinguish between the multiple gas laws.

Standard 12: Given a confined gas, explain the differences between the following laws: Boyle’s, Charles’, Avogadro’s and Gay-Lussac’s. Identify an online demonstration or prepare a demonstration of one (or more) of these laws and document each step of the law(s). Use an online editing tool to create a single written informative text with links to virtual demonstrations.

 Content Understandings

Extending Understandings

Upon successful completion of these tasks students will demonstrate the ability to:

 

  1. distinguish between the gas laws,
  2. recognize the importance of each gas law, and
  3. understand the significance between volume, pressure, gas and temperature.

 

To move students towards deeper understanding, they should be given opportunities to:

 

  • Recognize the correlation between the Gas laws.
  • Illustrate the gas laws using real world scenarios.
  • Utilize the Gas formulas to solve problems.

Support Strategies

If students are struggling to access this task, additional supports and strategies could be employed as students are engaging with the task.

  1. Describe what happens to pressure and temperature when you introduce 150 heavy particles to the chamber and then increase that number to 200 heavy particles.

 

  1. Observe and describe what happens if you hold (volume) constant, increase temperature to 500K and insert 150 heavy particles to the chamber.

 

b) What happens if you decrease the number of heavy particles to 50?

 

 

  1. Describe what happens when 50 light particles are introduced to the chamber with nothing as a hold constant.

 

b) Does the same thing happen if 50 heavy particles are introduced to the chamber? Explain.

 

 

  1. Design an experiment to determine the relationship between two gas properties, such as pressure and temperature.
