Particle Motion
Particles barely move and vibrate in place.
Solid
Tiny pieces (atoms or molecules) that make up all matter.
Particles
Adding thermal energy makes particles move _____.
How many states of matter are there?
Four
True or False: Particles move sometimes.
False. Particles are always moving.
The form that matter takes (solid, liquid, gas, or plasma) based on how its particles move.
State of Matter
Removing thermal energy usually makes particles move _____.
Slower.
This state of matter has no fixed shape or volume. Particles move freely and are far apart.
Gas
True or False: The state off matter depends on how much energy particles have.
True
Energy that moves from a warmer object to a cooler object.
Heat
Heating a substance _______ molecular motion.
Increases
This state of matter has a fixed shape and volume. Particles are packed closely together and vibrate in place.
Solid
This energy is associated with particle motion.
Thermal Energy
Ambient (average) coolness or heat in an area.
Temperature
As molecular motion increases, the space between molecules _______.
Increases
This state of matter has particles that are charged and move very fast. This state is found in our stars and lightning
Plasma
