The equations for the three classic gas laws, Boyle s law, Charles law, and Avogadro s law, can be combined into a single equation called the ideal gas law. 

Which gas law (Boyle s law, Charles law, Avogadro s law, or the combined gas law) would apply in each of the following scenarios Only the variables that change are given. You need to state any terms (P, V, T, or ri) that must remain constant for the gas law you choose to be correct. 

The most important gas laws (Boyle s law, Charles s law, Dalton s law, and the ideal gas law) involve the relationships between pressure (P), volume (V), temperature (T), and number of moles (n) of gas. We are already familiar with the measurement of temperature and quantity from our laboratory experience. Measurement of pressure is perhaps not as obvious.

The gas laws describe the interdependence of three variables— pressure, volume, and temperature— that determine the behavior of gases. One of the gas laws, Boyle s law, states how gas pressure and gas volume are related. Boyle s law applies to ideal gases, which obey all of the assumptions made by the kinetic theory. With a simple laboratory setup, you can test how well Boyle s law applies to real gases. 

In addition, I give you the sour and bitter details about acids, bases, pHs, and antacids. And I present the properties of gases. In fact, in the gas chapter, you ll see so many gas laws (Boyle s Law, Charles Law, Gay-Lussac s Law, the Combined Gas Law, the Ideal Gas Law, Avogadro s Law, and more) that you might feel like a lawyer when you re done. 

The first three gas laws (Boyle s, Charles s, and the combined) are very similar in that they all use the symbols P, V, and T. If you have narrowed down a gas law problem to one of these three, a simple approach is to use the combined gas law. It works in all three cases. If T is constant,... 

Four gas variables—vo/ume (V), pressure (P), temperature (T), and amount (n)—are interdependent. For a hypothetical ideal gas, volume changes linearly with a change in any one of the other variables, as long as the remaining two are held constant. These behaviors are described by gas laws (Boyle s, Charles s, and Avogadro s), which are combined into the ideal gas law (PV = nRT). Most simple gases behave ideally at ordinary pressures and temperatures. (Section 5.3)...
