Properties of Gases

Lab report for this lab:

Introduction

In your introduction, you should discuss properties of gases and the relationship they have to one another. It would be good to read Section in your textbook to help you in writing the introduction. In this lab, you will use a simulation published by the University of Colorado. This simulation is called a PHET simulation.

Procedure

This lab is based on the Gases Intro and Properties simulations. Please familiarize yourself with the program so that you can write the procedure section of your report before you actually tackle the program. The link to the PHET simulation and balancing game is below. Click on the link to launch the PHET simulation from the University of Colorado.

Gas Properties

Discussion

In this section, address how properties like the number of particles (moles), volume, temperature, and pressure are related to the ideal gas law. You will need to talk about how keeping variables constant can help you make light of the ideal gas law equation. Use evidence from your graphs as reasoning and verification for the information you gathered in the introduction.

Data/Calculations

Using the Gas Properties simulation, you will select certain variables to be held constant. The variable held constant will be the one not included in the data table.

 Temperature (K) Pressure (atm)
 Container Length (nm) Pressure (atm)

(We will use the length of the container to symbolize volume) *

 Number of Particles (moles) Container Length (nm)

Create three graphs in excel displaying the relationships identified in the data tables. Make sure to include titles, labels, R2 values, and linear fits.

Conclusions

Wrap up your lab with some thoughtful conclusions regarding the lab and the underlying principles. Include some of your major results. Please note that statements such as “This lab was fun” or “this lab was a waste of my time” will earn you 0 points. Such conclusions do not represent the thinking of a university student.
