Phases of Matter, Bond Forces, and Kinetic Molecular Theory (KMT)
To first understand how gases behave, we must be able to compare them to other phases of matter - namely solids and liquids. This comparison is based on bond forces and how particles behave when certain bond forces are present.

Gas Laws
The foundation of any study of gases is using mathematical models to describe KMT gas behavior. These mathematical formulas are referred to as "Gas Laws" and are summarized to the right.
Although knowing the first three laws is important, the simplest way to remember gas laws is to memorize the combined and ideal gas laws.

The following documents are the references we use in class for gas laws and partial pressures.

Intro Lab - Using Charles Law To Predict Absolute Zero
The Intro Lab for this unit involves using Charles Law to predict the temperature at which absolute zero occurs. At absolute zero, volume should theoretically be zero.

Skeptical Questions In Science
The skeptical question topic for this unit involves greenhouse gases, the carbon cycle and carbon footprints. Skeptical questions are thoughtful "Why-based" questions which address biases in scientific material. This type of question is not seeking scientific facts.

Gas Law Calculation Problem Grid and Gas Law Calculations
One of the major problems students have with gas law calculations is remembering all the conversions. In order to address this, at least in the beginning, we use an organizational grid to keep track of everything that needs to be juggled in a gas law problem.

Molar Mass of Butane Full Lab
The purpose of this lab is to determine the molar mass of butane gas by isolating and measuring a sample.
Questions:
What is the estimated lab value for the molar mass of butane gas?
How far off is this estimate from the mathematically calculated butane molar mass?
"If-Then-Due-To" Hypothesis: "If butane is collected in a lab setting, then the molar mass should be able to be calculated due to the mass of the gas occupying a specific volume."
Variables: (x) lab group; (y) molar mass
Constants: same balance; same butane source
Control: Calculated molar mass of butane = 58g/mol
