Kinetic theory |
Matter is made from particles (atoms, molecules, ions) The particles are in constant motion, except at absolute zero temp (0 K or -273^C) The distance between the particles is smallest between solids and largest between gases |
Matter is made from.. Particles are in constant.. Distance is smallest when..and largest.. |

|
Internal energy |
The total energy of particles within a substance Total internal energy = total kinetic energy + potential |
Total..within.. Equation is total k.. |
|
|
Temperature |
A measure of average kinetic energy in particles |
Average measure of.. |
|
|
Heat |
Energy that flows from areas of high temp to those of low temp |
Energy that flows from.. |
|
|
Fahrenheit, Kelvin equations |
F = 9/5 x ^C + 32 K = ^C + 273 C = K - 273 or (F-32) x 5/9 |

Heat capacity |
Amount of heat required to change the temp of an object by 1 degree |
Amount of heat require to.. |
|
|
Specific heat capacity |
Amount of heat required to change the temp 1kg of substance by 1 degree |
Heat required..1k.. |
