Common-Core Grade 8 - 8 Particle motion and changes of state
|
With an decrease in temperature, the particles loss kinetic energy and move slower
The process in which a solid changes directly to a gas is called sublimation
In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other.
do not move around freely
When matter cools down, its particles lose kinetic energy.
recall the properties
gas vibrate and move freely at high speeds. liquid vibrate, move about, and slide past each other. solid vibrate but generally do not move from place to place.
The decreased kinetic energy lets the particles come closer together.
do not have fixed positions.
