physical science unit 14

boiling occurs above and below liquid
evaporstion occurs just on the surface of liquid
condensation change from a gas to a liguid
thermal expansion heat makes an object bigger
freezing liquid turns into a solid 0C and 32F
melting solid turns into a liquid 100C and 212F
gases particles are spread out and con move freely no volume, no shape
liquids particles packed close together but can still move no volume, shape
solids particles close together and cant move is volume, and is shape
insulators dosnt allow a transfer of electricity or energy
conductors allow a transfer of electricity or energy
radiation heat that moves in waves
convection heat cycles around heat
conduction heat transfers
specific heat formula mass x specific heat x change in energy
specific heat amount of heat used to raise the tempature
heat matter at a lower temp.
thermal energy the total potential and kinetic energy of the particles in an object
Fahrenheit to kelvin convert f to c then c to k
Celsius to kelvin add 273
Fahrenheit to celsius (f-32) x .56
absolute zero no thermal energy -273k
Celsius to Fahrenheit (c x 1.8) + 32
kelvin (physical science) 237k-freezing 373k-melting
celsius in all other countries 0C-freezing 100C-melting
fahrenheit used only in u.s.a 32F-freezing 212F-melting
