1
Q
5 parts of particle theory
A
particles move faster when heated particles attract each other all matter is made up of particles you cannot see particles are always moving particles have spaces between them
2
Q
thermal energy
A
the total kinetic energy and energy of attraction of all the particles of a material
3
Q
kinetic energy
A
energy that all moving objects posses a particle has more kinetic energy when moving faster and less kinetic energy when moving slower
4
Q
temperature
A
the measure of average kinetic energy of the particles of a substance
5
Q
gas particles
A
move very quickly vibrate, rotate and move past each other have very large spaces in between them are easy to compress kinetic energy=high
6
Q
liquid particles
A
move quickly
vibrate, rotate and move around each other
are fairly spaced out
resist being squeezed close together
will not break all the way apart from each other
kinetic energy: medium
7
Q
solid particles
A
vibrate
cannot move around each other
are packed close together
kinetic energy=low
8
Q
expansion
A
gas= alot
liquid= a little
solid=very little
