State Of Matter 2 Flashcards
A gas is composed of molecules that are
Spread far apart
Gas or vapor does not have a fixed shape or
Volume
Gases volume or shape are dependent on its
Container
Unlike a liquid, a gas will expand to
Fill up its container
Gas molecules are relatively
High kinetic energy
High kinetic energy means they _ quickly
Move
High kinetic energy means they are able to overcome
Attraction between them and separate
_ molecules move quickly and are able to overcome the attraction between them and separate
High kinetic energy
_ cannot be compressed
Solids
_ can be compressed a little
Liquids
_ can be compressed
Gas
Compressibility measures the _ resulting from applied pressure
Change in volume
Phase changes are the changes in _ affecting matter (2)
Temp
Pressure
The changes in temp or pressure affecting matter are called
Phase changes
(Phase changes) _ is when solid turns into liquid
Melting
The _ point is the temp at which solids melt
Melting
Heat increases the _ inside the solid
Kinetic energy
(Melting) increased _ breaks attraction between molecules and allows them to move away from each other (2)
Energy
Movement
(Phase change) _ is what happens when liquids become a solid
Freezing
(Freezing) as the temperature decreases _
Molecules inside have lower kinetic energy
