Chemistry ch12 Flashcards
What does the kinetic molecular theory describe
The behavior of gasses in terms of particles in motion
The volume of gas particles in themselves are very _ compared to the volume of the sample
Small
Because gas particles are far apart, there are no significant attractive or repulsive _ between gas particles
Forces
Gas particles are in constant and _ motion
Random
The collisions between gas particles are _ : that is, no _ energy is lost
Elastic; kinetic
What causes a phase change
The addition or removal of emerge
How does the kinetic energy of particles vary as a function of temperature
They are directly proportional
What does Graham’s law state
That the rate of effusion for a gas is inversely proportional to the square root of its molar mass
Do lighter particles diffuse faster than heavier particles
Yes
What is point a called and what happens here
Triple point, the temperature and pressure at which three phases of a substance can coexist
What is point b and what happens here
Critical point, distinction between liquid and gas can no longer be made
