Chapter 5: Gas Laws Flashcards
Describe movement of gas molecules
Depends on temperature and kinetic energy not every molecule moving at same speed
Average kinetic energy of the molecules
Temperature
SI unit of temp
Kelvin
When is a gas at absolute zero
At 0 kelvin and 0 volume
Size of container it
Volume
No energy is lost
Elastic collision
What happens when gases mix together and why
They form a solution bc they don’t exhibit intermolecular forces bc too far apart
Impacts of the molecules on the container wall
Pressure
What law do you use when conditions are not changing
Ideal gas law
Pressure due to any individual component in a gas mixture
Partial pressure
Explain kinetic molecular theory
Gases consist of molecules that are in continuous random motion
Volume of molecules is negligible compared to the volume of the gas container
Molecular attractions and repulsions are negligible
Molecules undergo elastic collisions
The average kinetic energy is proportional to the absolute temperature (kelvin)
Gas that confirms all five gas laws
Ideal gas
What happens under conditions of high pressure low temperature
Gases deviate from their behavior
How do gases deviate from their behavior
Molecules become more tightly packed and their volume is no longer negligible
Attractive and repulsive forces start to take hold
How do the sizes of gases come into play
Small simple gases will behave ideally longer that that of larger gases
