It is OK to use your textbook or lecture notes from class, but if you can answers the questions without it that is OK too.

Do not press the RETURN or ENTER key while you are answering these questions. Your browser will interpret either the same as clicking on the Submit key.

Answer all of the questions below. If you do not know an answer enter CNA. However, it will help me the most if you answer each question with your best intuition/idea about what would be a reasonable answer.

In this ACA we will investigate the effect of different variables on the pressure exerted by an ideal gas. To do this investigation we will use a simulation. Clicking on this link above will produce a new page with the simulation. If your browser is not accessorized properly to run this software try downloading the latest version of Java software. That should accessorize the browser so it can run the simulation. You may have to quit and re-start your browser for the software to work properly.

 

1. Setup the simulation as described in each of the Experiments below and record the pressure.

2. Which of the following is an explanation for your observation?(Choose one)

there are more collision;

Because the average speed of the particles has increased the force of the collisions with the walls of the container will be greater and a corresponding increase in pressure.

5. Is there anything about the questions that you feel you do not understand? List your concerns/questions.

6. If there is one question you would like to have answered in lecture, what would that question be?
