CHEMISTRY CH 10 Flashcards
Kinetic molecular theory
How molecules move
Phase
State of matter
Equilibrium
Two opposing changes occur at same rate
Crystalline
Repeating pattern of crystals
Amorphous and example
No patterns, supercooled liquids
Plastic
Equilibrium vapor pressure
Pressure forms a vapor at equilibrium with its liquid
Boiling point
Temp when at EVP equals atmospheric pressure
Freezing point
Liquid and solid are at equilibrium, pressure is 1 atom
Enthalpy
Energy to change state
Triple points
All 3 points coexist
Critical point
Past it, only vapor exists
Specific heat
What’s the equation?
Heat to change temperature
Why can gases expand
Because of random motion
Hydrogen bonding
Hydrogen is bonded to something
Solid is less dense than the liquid because of
Hydrogen bonding
