Since we have one week to deal with Gasses, I will simply provide the information and will NOT be doing any demos or labs. At the bottom of this webpage, there is a link to a simulator/animation to better understand the "Gas Laws" (Boyle's, Charle's, and Guy-Laussic Laws).
We will first look at the Particle view of Gasses including the 4 main parameters/characteristics of gas particles, under General Information on Gasses.
General Information on Gases
So now you should know that Gas particles have four parameters:
a) Volume, volume gas particle occupy not actual size of particle, usually in mL or L (symbol V)
b) Number of gas particles, usually in V), in number of moles (symbol n)
c) Gas pressure (I think of number of hits on the container wall for all the gas particle in substance), many different unit but atm is most used
MOST IMPORTANT ONE: d) Temperature, energy that the gas particle has, ALWAYS in Kelvin temperature scale (K)
Now we will start taking a look at Gas calculations. There are "a lot" of gas calculations "out there" so I have found it best to organize then into different group. However, all of the equations are derived or comes from the Ideal Gas law (that will be explained below).
Unlike some of the other chemical concepts, for gas calculations, I think it is important to have an overview of all the gas calculations before getting dealing with any specific gas calculation.
SO the next section deals with Overview. Before you start looking at the Youtube video, I would like to emphasize what I call a Condition. Each condition is a gas (actually a lot of gas particles) that can be describe with the 4 parameters (V,n,P,T). So there are 2 possibilities:
a) 1 Condition problem: this is where one is just describing the gas using the 4 parameters (no action verbs in question/problem
b) 2 Condition problem : this is where one is "doing something" to the gas SO there is the initial condition (Condition 1) and then after you do something (i.e. increasing temp, decreasing volume), you have the new condition (Condition 2). Usually, people use 1 and 2 as subscripts in the equation.
Here is more in-depth overview.
Overview of Gas Calculations
All Temperatures used in Gas Calculations MUST BE in KELVIN (K) not Celsius or Fahrenheit!!!!!!!
1 Condition Gas Problem (can tell if there is no action verbs in problem)
Ideal Gas Law
2 Condition Gas Problems (See action verbs in problem, expand or decrease,etc)
General Information for 2 Condition Gas Problems
Boyle's Law
Guy - Lussaic's Law (No Name Law)
Avogadro's Hypothesis
Charles' Law
Combined Gas Law - Where 1 parameter (n=number of moles) is held constant , 3 parameters vary
