Solid
strong attraction
molecules constantly vibrating(thermal)
tightly packed
fixed volume and shape
Liquid
particles cling together
more vibration(thermal)
definite volume
no definite shape
Gas
weak attraction
more motion(thermal)
no definite shape or volume
HAS volume
Plasma
most common
matter consisting of positive and negative charged particles
no definite shape or volume
Melting
solid--> liquid
heat of fusion= energy required to turn 1kg of matter from solid to liquid
Freezing
liquid ---> solid
heat of fussion= energy required to turn 1kg of matter from a liquid to a solid
Vaporization
liquid ---> gas
Heat of vaporization= amount of energy required to turn 1kg of matter from a liquid to a gas
Boiling
liquid---> gas
convection
less pressure= easier to boil
heat of vaporization= amount of energy required to turn 1 kg of matter from liquid---> gas
Condensation
heat of vaporization_---> amount of energy released going from gas---> liquid

gas--> liquid
Evaporation
liquid--> gas
heat of vaporization
amount of energy required to turn liquid to a gas
on the surface
Conduction
direct contact
colliding molecules
Radiation
thermal energy through electromagnetic waves
microwave, sun....
Convection
thermal energy traveling through fluids
convection current
Kinetic energy
energy in motion
Potential energy
stored energy that has the potential to create change or motion
Radiant energy
energy transformed through electromagnetic waves
Insulator
a material that does not allow heat or electrons to move through it easily
Conductor
a material that easily allows the flow of electricity
Thermal Energy
the total kinetic and potential energy in a substance.
Law of Conservation of energy
says that energy can neither be created nor destroyed
Specific heat
The amount of heat that must be absorbed or lost for 1 gram of a substance to change its temperature by 1°C.
Motion
the movement of particles
Thermal expansion
the expansion of matter when it is heated
Chemical energy
energy stored in chemical bonds
Electrical energy
the energy of moving electric charges
Sound energy
Energy caused by an object's vibrations
Nuclear energy
energy stored in the nucleus of an atom
Gravitational energy
potential energy that depends on the height of an object
Stored Mechanical energy
potential; compressed or stretched objects that store energy
