Question
Why do molecules in a solid move more slowly thanb tthose in a liquid? What is it about the different substances?
Thanks!
Hi Tim,
To answer your question properly, I need to explain the states of matter and the reason for solids, liquids, gases, and plasmas. The short explanation is that each state of matter has a different inter-molecular energy as compared to the molecules' kinetic energy. To understand this "kinetic theory of matter", I refer you to an excellent web site http://www.visionlearning.com/library/module_viewer.php?mid=120
That website will more fully explain the reason molecules in a solid move more slowly (and therefore have less kinetic energy) than molecules in a liquid.
