Kinetic Model of Matter 101

Main Idea(s) Matter is made of tiny particles (atoms or molecules) that are in random and continuous motion. Effects of Temperature on Molecular Motion When temperature increases, the average kinetic energy of the molecules increases. This leads to increase in the average speed of the molecules, resulting in the particles collide with the wall/other particles … Read more

Sound 101

What you must understand Sound is a form of energy that is transferred from one point to another as a longitudinal wave. Production of sound: vibrating sources placed in a medium. Transmission of sound: sound travels as a series of compressions (C) and rarefactions (R) in the medium. The particles simply oscillate back and forth … Read more
