Conduction of
heat is
essentially the transfer of heat from
one object to another through physical
contact.This transfer occurs on the
molecular level when heat is absorbed on
the surface of one object and
transferred to the other object.The
molecules
in the first object move more quickly as
the heat is absorbed. They
then bump into their neighbors and pass
that energy on.This
process continues until both objects
reach equilibrium where both object’s
temperatures are the same.
A lot of times the
rate of
heat transfer is needed to understand how
well an insulator or conductor a
material is. This can be found using
the equation and figure found below:
Q is the heat
transferred
in the time interval t, so Q/t is the rate
of heat transfer.K is the thermal
conductivity of the material,
A is the cross sectional area of the object,
d is the length of the object, and
the temperature difference between the two
materials is (Thot-Tcold).
