Arrangement of the particles

# data[].attributes.body
When the temperature of the surrounding increases, the particles gain heat energy from it, therefore the molecules move

faster because the particles are far apart from one another.

But when the temperature decreases, the particles loses heat energy to the surroundings as a

result, the molecules move slower, because they are closely packed together and have little or no space to move about.

We identify different states of matter, revise the processes required to change state, explain why matter exists in different states by using the Kinetic Molecular Theory as well as introduce the concept of inter-molecular forces.

"Small pieces of metal shot and bb's are good models for the kinetic-molecular theory of matter and the properties of gases." This video is part of the Flinn Scientific Best Practices for Teaching Chemistry Video Series, a collection of over 125 hours of free professional development training for chemistry teachers - http://elearning.flinnsci.com ATTENTION: This demonstration is intended for and should only be performed by certified science instructors in a safe laboratory/classroom setting.
