conduction and convection Flashcards
where does conduction mainly occur
in solids
what is conduction
the process where vibrating particles transfer energy to neighbouring particles
how is energy transferred to an object by heating
energy is transferred to the thermal energy store of the object
what happens when the particles in an object are being heated
they vibrate more and collide with eachother
what is thermal conductivity
the measure of how quickly energy is transferred through a material in this way
materials with a high thermal conductivity transfer energy between particles quicker
where does convection occur
only in liquids and gases
what is convection
where energetic particles move away from hotter to cooler regions
who is energy transferred in convection
by heating to the thermal store of liquid or gas
what happens when you heat a region of gas or liquid
they move faster
