Transcript of Kinetic Theory Of Matter
Kinetic Theory of MatterBy Emily Adamson
What’s the Kinetic Theory of Matter?It’s a theory that helps explain difference
between the states of matter.
The Kinetic Theory of Matter states…Matter is made up of constantly moving
molecules or atoms.
Under the Kinetic Theory of Matter…Solids’ particles are so close to each other
that they only vibrate in place.
Under the Kinetic Theory of Matter…Liquids’ particles have more space to move
than solids, but there is still an attraction between them.
Under the Kinetic Theory of Matter…Gases’ particles are far apart and move around because the attraction is so low it
can be disregarded.
Substances can change into different phases of matter and back.
WHY DOES THIS HAPPEN?
First, we need to know about….Kinetic Energy is energy of motion. There are multiple forms, such as:VibrationalRotationalTranslational.
First, we need to know about….
Thermal energy is total kinetic energy of all of a substance’s atoms and molecules .
Kinetic Energy
First, we need to know about….
Temperature is the average amount of kineticenergy in an object.
Matter can change into different phases becausethe exchange of thermal energy between a
substance and the environment.
Everything wants to be in its lowest state of energy. That’s why the exchange occurs!
Thermal Energy •Increases as temperature increases•Increases as kinetic energy increases
Temperature •Increases as kinetic energy increases•Increases as thermal energy increases
Kinetic Energy •Motion increases as temperature increases•Increases as thermal energy increases
Overall, when temperature increases, atoms andmolecules’ motion increases (kinetic energy).Thermal energy increases because the total
amount ofkinetic energy increased due to the temperature
change.
THEY’RE ALL INTERTWINED!
