Question | Answer |
---|---|
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 |
V1/T1=V2/T2 | Formula for Charles Law |
Combination of Boyle's & Charles Law | Combined Gas Law |
P1 V1/T1=P2 V2/T2 | Formula for Combined Gas Law |
