Particle Theory
Question | Answer |
---|---|
anything that takes up space and has mass | matter |
all matter is made up of | particles |
the particles of matter are always | moving |
between particles, there is | space |
particles are ___________ to one another | attracted |
the energy an object has due to its motion is this kind of energy | kinetic |
this is a measure of the average kinetic energy of something's particles | temperature |
the form of matter with a fixed shape | solid |
this form of matter has no shape, but has a certain volume | liquid |
this form of matter has no shape or certain volume | gas |
the two-word term that means the volume of something increases when the temperature increases | thermal expansion |
the two-word term that describes how the volume of something shrinks when it cools | thermal contraction |
the three-word phrase that describes the change from any state of matter to another | change of state |
the change from solid to liquid | melting |
the change from liquid to solid | freezing |
the change from liquid to gas | evaporation |
the change from gas to liquid | condensation |
the change from solid to gas | sublimation |
the change from gas to solid | deposition |
the temperature at which something changes from a solid to a liquid is called its | melting point |
the temperature at which something changes from a liquid to a gas is called its | boiling point |
this is a graph or plot of temperature vs time | heating curve |
