Chapter 10 Flashcards
Kinetic Molecular Theory
explains the behavior of gases based on the motion of their particles
what is a gases average kinetic energy proportional to?
absolute temp
what kind of collisions do gases engage in?
elastic
what changes a gases volume?
temp and pressure
effusion
gas leaking through small holes from a high pressure are to a low pressure area
u
speed of molecules
n
number of moles
smaller mass=
higher speed
atmospheric pressure
pressure exerted due to gravity acting on air above Earth’s surface
1 atm=
101.325 Pa
1atm=
1.01325 bars
1 atm==
760 mmHg
absolute temperature
temp expressed on the Kelvin scale whose zero value is absolute zero
ideal gas
gas whose behavior is predicted by the linear relations defined by the combined gas law
