Unit 3 Flashcards
Extensive properties
volume, mass, moles, energy
Intensive properties
temperature, pressure, density
Boyles Law
P1V1 = P2V2, inverse relationship of pressure and volume
Charles Law
V1/T1=V2/T2, direct relationship of volume and temperature
Dalton’s Law
Ptot=P1+P2+P3, additive nature of gas partial pressures
Avogadro’s Law
equal volumes of gas at constant temperatures (T) and pressure (P) have the same number of moles (n)
(V/N=V/N)
Gay Lussac’s Law
at a constant pressure and temperature, gases combine in simple proportion by volume , pressure is directly proportional to temperature when volume is constant
(P/T=P/T)
open system
matter and energy being exchanged
closed system
only energy being exchanged
isolated system
no matter or energy exchanged
