Heat travelling by direct
particle to particle
contact is called
_____________.

H 300
Heat moving by waves,
such as the sun’s heat
reaching us is called
what? Give an example.
Heat 300
Radiation; standing near a fire
and feeling warmth, a piece of
bread warming up in a toaster
Jeopardy Home
H 400
On a hot summer day, as
you walk across the beach,
your feet get hot. Explain
the two kinds of heat
transfers that are
happening.
Heat 400
Radiation from the sun is warming
the sand, your feet are getting
warm because of contact with
the sand, which is conduction
Jeopardy Home
H 500
Heat energy will travel
from one substance to
another until the two
substances have the same
temperature. What is
this called?
Heat 500
Thermal Equilibrium
Jeopardy Home
H 600
In convection, hot air/liquid
rises forcing cold air down in
a continuous pattern,
creating a current. Why
does the hot air/liquid rise?
Heat 600
The heated fluid rises because the
particles are moving faster, which
causes the substance to become
less dense.

K.M.T. 400
If I begin to melt a metal,
describe what is
happening to the
energy of the metal
molecules?
Kinetic Molecular Theory 400

faster, and the temperature will
increase until the phase change
occurs, at which point the
temperature will remain constant
until the phase change is
complete.

• When water boils, some of
its molecules have enough
_____________ to break the
attraction to neighboring
molecules. Explain force of
attraction between
molecules.

K.M.T. 600
Describe what happens
to the kinetic energy of
water molecules as
water freezes?
Kinetic Molecular Theory 600
As water molecules decrease in
temperature, they lose kinetic energy.
Once water molecules have frozen, their
kinetic energy has decreased to the point
where the molecules vibrate in place
instead of moving freely.
