Now You Know

After completing this tutorial, you will be able to complete the following:

  • Explain that the volume of any quantity of gas is directly proportional to its temperature.
  • Describe the equation for Charles’s law as V1/ T1 = V2/ T2.
  • Explain that as the temperature of an ideal gas increases, the volume also increases.
  • Explain that as the temperature of an ideal gas decreases, the volume also decreases.
  • Recognize a plausibly correct graph for volume versus temperature.

Everything You'll Have Covered

Gas particles are in constant motion. Temperature and volume are influenced by this motion under conditions that are constantly changing. When pressure is held constant, temperature and volume have a direct relationship. This means that as temperature increases, the volume of the sample also increases. And as temperature decreases, the volume decreases. The equation that represents this relationship, known as Charles's law, is This equation shows that the conditions of temperature and volume change while pressure is kept constant.
