States of Matter
is anything that has mass (weighs something) and occupies space.
the study of matter
a person that studies chemistry
3 basic states of matter
solid, liquid, and gas
molecules are really close together
molecules are spread out a little but not real far
molecules are far apart and free to move in any direction
speed of SOLID atoms
speed of LIQUID atoms
speed of GAS atoms
What has a DEFINITE shape?
What has an INDEFINITE shape?
LIQUIDS & GASES
What has a DEFINITE volume?
SOLIDS & LIQUIDS
What has an INDEFINITE volume?
when heat is ADDED
when heat is REMOVED
is changing from a SOLID to a LIQUID
this is the temperature at which a SOLID melts
is changing from a LIQUID to a GAS
is changing from a SOLID to a GAS without passing through the LIQUID state
this is the temperature at which a LIQUID changes to a GAS
is changing from a GAS to a LIQUID
is changing from a LIQUID to a SOLID
this is the temperature at which a LIQUID freezes
is the smallest unit of matter
measures the movement of particles
the SLOWER the movement of particles
the COLDER it is
the HIGHER the movement of particles
the HOTTER it is
a tool used to measure temperature
is the transfer of energy from a higher temperature to a lower temperature
