Unit 4B Flashcards
deposition
the change of state from a gas to a solid
sublimation
the change of state from solid to gas
Describe the particles in a solid
Vibrate, close together (Stronger IMFs and low kinetic energy)
Describe particles in a liquid
Particles flow freely and are relatively close together (high kinetic energy and neutral IMF)
Describe particles in a gas
constant random motion and far apart (low IMF and highest kinetic energy)
What is Kinetic Molecular Energy?
A theory that says the states of matter are composed of particles that are constantly in motion
Describe the relation between kinetic energy in matter and temperature?
As temperature increases, so does the kinetic energy (high temperature=high energy)
Solids are favored at what conditions?
low temperature and high pressure
Gases are favored at what conditions?
high temperature and low pressure
triple point
the temperature and pressure at which the solid, liquid, and vapor phases of a pure substance can coexist in equilibrium.
critical point
a point of pressure and temperature where gas and liquid become indistinguishable
Gas pressure is caused by
gas molecules colliding with surfaces of containers
Inverse relationships
one increases where the other decreases (inverse of each other)
direct relationships
increase or decrease together
How is pressure and volume related?
inversely
