Conduction occurs in
Solids
Convection occurs in
Liquids
and
Gases.
Radiation occurs in
empty
space.
CONDUCTION
:
Vibrating
particles
transfer
energy
to
neighbouring
particles.
Metals
have a
high
thermal conductivity.
Plastics
have a
low
thermal conductivity.
CONVECTION
: Where
energetic
particles move from
hotter
to
cooler
regions.
In
CONVECTION
the
fluid
(liquid or gas) becomes
less dense
as the particles are being
spread
out
because they are being
heated
.
In
CONVECTION
if there is a
constant
heat source. There will be a
CONVECTION
CURRENT
.
As the now cool particles will be
hot
again
and
cool
again.
Thermal Conductivity
is how
well
a
material
conducts
energy.
Convection currents
occur in
limited
space.
