Relationship Between Temperature and Pressure
On Lab.
On Graph.
Temperature and Pressure have a direct relationship.
The extrapolated line hits the pressure of O kPa at approximately 15 K.
If everything was done perfectly the temperature should have been O K.
Percent Error = (EV -TV)/TV * 100
Percent Error = (-258 K+273 K) / -273K *100
Percent Error = 5.49 %
One of the assumptions that one can derive from the Kinetic molecular theory is that as the temperature decreases the velocity of the particles will also decrease. This decrease in the velocity will prevent the particles from bouncing off of the walls of their container and each other as much, decreasing the pressure.
The Kinetic-Molecular Theory for gas is centered around the beliefs that gases are composed of
