Most of the gas laws depend upon various combinations of volume (V), temperature (T), pressure (P), and moles (n). In some cases, all four are important; in others, one or two are held constant. Although a number of pressure or volume units will work, all temperatures used in the calculations must be in kelvins. Graham’s law is the only law in this chapter that doesn’t depend upon V, T, P, or n.
The Problems You’ll Work On
In this chapter, you work with gases in the following ways:
Converting units of pressure
Using Boyle’s law, Charles’s law, and Gay-Lussac’s law
Finding pressure, volume, and temperature with the combined gas law
Relating volume to moles with Avogadro’s law
Working with the ideal gas law
Finding partial pressures with Dalton’s law
Exploring effusion ...
