### Diffusion of Gases, Sig Figs, Scientific Notations, Gas Laws

the random movement of particles from a high concentration to a low concentration Diffusion
Gas diffusing in a gas Spraying perfumes in a room
Gas diffusing in a liquid O2 diffusing into the blood
Liquid diffusing in a liquid Food coloring diffusing in water
Heavier particles move slower than lighter particles Kinetic Molecular Theory (KMT)
Diffuses the fastest Gases
Diffuses the slowest Solid
Studying how temperature, pressure, & volume affect fixed amount of gases Gas Laws
As one variable increases the other would decrease; an indirectly proportional relationship; Boyle's Law
P1 V1=P2 V2 Formula for Boyle's Law
Used for very small & very big numbers Scientific Notation
If one variable increase the other increases; a directly proportional relationship Charles Law
