Gay-Lussac Law
- As temperature drops, particles lose Kinetic Energy and speed.
- They ultimately reach a point where their Kinetic Energy = 0.
- The particles stop bouncing off the walls of the container and the pressure exerted becomes zero.
- This is absolute zero.
Absolute Zero = -273ºC
Kelvin scale of temperature/Absolute temperature
0K = -273ºC
0ºC = 273K
0K = -273ºC
0ºC = 273K
Relationship between Pressure and Absolute Temperature
Pressure and Temperature are directly proportional when temperature is measured in Kelvin because the graph is a straight line that goes through the origin.
If you increase the temperature, you will increase the pressure.
Temperature in Kelvin = average Kinetic Energy of the gas particles.
If you increase the temperature, you will increase the pressure.
Temperature in Kelvin = average Kinetic Energy of the gas particles.
