Chapter 7 [Kinetic Model Of Matter]
BROWNIAN MOTION
- irregular motion of smoke particles in the air
- occurs only in fluid that has ability to flow / particles that are able to move freely [gas, liquid]
-->smoke particles at higher temp causes the motion of smoke particles to be more vigorous and air molecules move at greater speed
--> air molecules bombard smoke particles more vigorously
--> larger amt of thermal energy is converted to KE when temp increases, hence, molecules move faster
