conduction Flashcards
What is conduction
Heat transfer in solids
Where does heat travel
Heat travels from hot to cold
What happens if there’s a larger temp difference
The larger the temperature difference, the faster the rate of heat transfer .
How is heat transferred in solids
Particles vibrate + pass along energy
why are metals good conductors of heat
they have free electrons that can carry thermal energy very quickly.
What are non metals poor/good at
poor conductors/ good insulators
How is the energy passed
by direct contact
what happens when energy is transferred from the hotter object to the colder object
The hot object cools down and the cold object heats up
what are materials that easily transfer energy called
conductors
Where does thermal energy flow
through the material itself
