a solid that is made up of crystals in which particles are arranged in a regular, repeating pattern-melts at a specific temp
A solid made up of particles that are not arranged in a regular pattern--does not melt at a distinct temp.
the result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together
The temperature at which a substance changes from a solid to a liquid; the same as the freezing point, or temperature at which a liquid changes to a solid-- water melts at 0ºc
The process that occurs when vaporization takes place inside a liquid as well as on the surface
The temperature at which a substance changes from a liquid to a gas; the same as the condensation point, or temperature at which a gas changes to a liquid
The change in state from a solid directly to a gas without passing through the liquid state
a principle that describes the relationship between the temperature and volume of a gas at constant pressure
a term used to describe the relationship between two variables whose graph is a straight line passing through the point (0,0)
a term used to describe the relationship between two variables whose graph forms a curve that slopes downward
Boyle's Law on a Graph
Temp is kept constant
Charle's Law on a Graph
Pressure is kept constant
Melting Point Particles
particles of the solid are moving or vibration so fast that they break free from their fixed position
Freezing Point Particles
particles of the liquid are moving so slow that they begin to start to form regular patterns
Boiling Point Particles
vaporized water molecules form bubbles bellow the surface and then start to rise to the surface
How does a Hot Air Balloon Descend/Rise
When the air cools the air becomes more dense. to rise the air is heated and air becomes less dense.
the temperature at which a substance changes from a liquid to a solid-- water freezes at 0ºc
Why does air leak out of a basketball even though its a small hole
higher pressure in the ball results in gas particles hitting the inter surface more often so particles inside reach the hole more often exasape therefore the pressure inside the ball drops until = to the outside pressure
