Learn what is meant by the term gas laws. When seventeenth-century scientists began studying the physical properties of gases, they noticed some simple relationships between some of the measurable properties of the gas. Take pressure P and volume V , for example. Scientists noted that for a given amount of a gas usually expressed in units of moles [n] , if the temperature T of the gas was kept constant, pressure and volume were related: As one increases, the other decreases. As one decreases, the other increases. We say that pressure and volume are inversely related. There is more to it, however: pressure and volume of a given amount of gas at constant temperature are numerically related.
A gas law A simple mathematical formula that allows one to model, or predict, the behavior of a gas. Figure 6. One can also plot P versus V for a given amount of gas at a certain temperature; such a plot will look like the graph on the right. Tactics for working with mathematical formulas are different from tactics for working with conversion factors. First, most of the questions you will have to answer using formulas are word-type questions, so the first step is to identify what quantities are known and assign them to variables.
Second, in most formulas, some mathematical rearrangements i. The rule is that to find the value of the unknown variable, you must mathematically isolate the unknown variable by itself and in the numerator of one side of the equation. Finally, units must be consistent. There are also two volume variables; they also must have the same unit. Example 3 A sample of gas has an initial pressure of 2. Its pressure changes to 1. What is the new volume if temperature and amount are kept constant? Solution First, determine what quantities we are given. This final volume is the variable we will solve for.
