Particle Theory
This happens to particles when heated
move faster and farther apart
type of heat transfer as soup is heated
convection
a measure of the quantity of space taken up by an object
volume
State where particles are the closest together
solid
Ice changing to water
melting
What particles make up
all matter
type of heat transfer by the sun's rays through space
radiation
thermal expansion
State where the particles are farthest apart
gas
water droplets forming on the outside of a cold glass
condensation
moving randomly
type of heat transfer when hot air rises
convection
a substance that lessens heat transfer
insulator
states that change shape based on their container
liquid and gas
a liquid becoming a solid
freezing
the number of main ideas about particle theory
5
type of heat transfer that heats up a pan on the stove
conduction
a measure of average heat transfer
temperature
state that has the most energetic particles
gas
a liquid changing to a gas
evaporation
Name 2 ideas behind particle theory
made up of tiny particles, empty space between, moving randomly all the item, faster and farther apart when heated, attracted to one another
type of heat transfer when your tongue touches a hot slice of pizza
conduction
Value given to the amount of resistance to heat loss in an insulating substance
R-value
states that have a definite volume
solid and liquid
a solid changing directly to a gas
sublimation
