Charles Law Graph

Charles's Law Overview

• Definition: Charles's Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) when the pressure is held constant.

Graphical Representation

• Volume vs. Temperature Plot:

  • The graph displays gas volume plotted against temperature.

  • At about 70°C, the gas has a volume of 60 mL.

  • As the temperature decreases to around -100°C, the volume of the gas decreases linearly to 30 mL.

Observations

• Temperature Interval:

  • The significant change occurs as the gas is cooled from approximately 70°C to -100°C.

  • As the temperature drops, the gas volume drops linearly, demonstrating the principles of Charles's Law.

Conclusion

• This relationship illustrates that as gas temperature decreases, so does its volume, supporting the concept that gas behavior can be modeled using Charles's Law.
