Summary:
- The combined gas law expresses the relationship between the pressure, volume, and absolute temperature of a fixed amount of gas.
- Boyle’s, Charles's, and Gay-Lussac's laws can all be easily derived from the law.
- The modern refrigerator takes advantage of the gas laws to remove heat from a system.
- Both the increase in pressure and the decrease in temperature cause the volume of a gas sample to decrease.
- Since both changes are relatively small, the volume does not decrease dramatically.
