Heat is the transfer of energy between
objects at different temperatures
which causes temperatures of both
objects to change
What is the difference between
Heat + temperature?
Row 1, Col 1
Convection is the transfer of energy
as heat by the movement of liquid or
gas / ex. in a room it is warmer near
the ceiling than near the floor
What is convection + give an
Example of convection ?
1,2
Conduction takes place when energy
is transferred from one particle to
another without the movement of
matter. / ex when you hold a pot of
boiling water over a fire and the
metal handle becomes hot.
What is conduction + give an
Example of conduction?
1,3
The Calorie and the joule.
What two units are used
to measure heat?
1,4
Thermal energy is the total
kinetic energy of all particles in
a substance.
What is thermal energy?
1,5
-One substance would have more
thermal energy than another even if
they were at the same temperature
because it must be larger and
contain more particles.
Why would one substance have
more thermal energy if two
substances are at the
same temperature?
2,1
1 calorie is the amount of energy
needed to raise the temperature of 1
gram of water by 1 degree Celsius;
therefore, 100 calories are needed to
raise the temperature of 10 grams of
water by 10 degrees Celsius.
What is the relationship
between calories and
temperature?
2,2
An insulator is a material that is a poor
conductor of heat./
What is an insulator?
2,3
The kinetic theory of matter
states that all of the particles
that make up matter are
constantly in motion.
What is the kinetic theory
of matter?.
2,4
-A thermometer is used to
measure temperature.
Give an example of a tool
used to measure temperature.
2,5
- The freezing/melting point of
water is 0 °C and the boiling
point of water is 100 °C.
What is the freezing/melting point
of water in Celsius
and what is the boiling point of
water in Celsius?
3,1
-The warmer the temperature, the
quicker the particles move. The
cooler the temperature, the slower the
particles move.
What is the relationship
between temperature and
movement of particles?
3,2
The freezing point of water is 273 K.
What is the freezing point
of water on the Kelvin scale?
3,3
- Potential energy is the energy stored
due to an object’s position, condition,
or chemical composition.
What is potential energy?
3,4
-The sum of all energy does
not change; instead it can be
converted into other forms.
What is the law of conservation
of energy?
3,5
Chemical energy.
What type of energy is
stored in a battery?
4,1
-Potential energy is the energy that an
object has due to position, condition, or
chemical composition.
-Gravitational potential energy
increases as the object’s height
increases.
What is gravitational
potential energy?
4,2
-The mass of the car. The object with
the greatest mass has the greatest
kinetic energy when the objects are
moving at the same speed.
If cars are moving at the same
speed what can give
one car more kinetic
energy than the other?
4,3
Radiation is the transfer of
energy by electromagnetic
waves. An example is a solar
cooker.
•Define radiation and give
•an example of a
•practical use of radiation.
4,4
Chemical- is a form of potential
energy. It depends on the kind of
atoms and their arrangements.
Food is an example of chemical
energy.
Define chemical energy
4,5
Kinetic- is the energy of an
object that is in motion.
Define kinetic energy
5,1
Electromagnetic- is energy
transmitted through space in
the form of electromagnetic
waves.
Define electromagnetic energy
5,2
Electrical- is the energy that
results from the position or
motion of charges particles.
Define electrical energy
5,3
-An example is a slingshot.
Give an example of
potential energy.
5,4
Ex. Plastic is an insulator, or a
poor conductor of energy as
heat
Give an example of an insulator
