What is 37.0 degrees
Celsius on the
Fahrenheit scale?
98.6ºF
What is 175ºF on the
Celsius scale?
79.4ºC
What is –175ºC on the
Kelvin scale?
98 K
As the kinetic energy of
the molecules in a
substance increases, the
_____ also increases.
temperature
The transfer of energy
as heat caused by the
collision of molecules is
called
conduction.
The transfer of energy
by the movement of
fluids or gases with
different temperatures is
called
convection.
Energy from the sun
reaches Earth by
radiation only.
Convection currents rise
in air because
cool air descends and
hot air rises.
Which method of energy
transfer does not involve
movement of matter?
convection.
radiation.
conduction.
radiation.
How much heat energy
will cause the
temperature of 7 kg of
carbon to increase its
temperature by 15 K?
The specific heat of iron
is 449 J/kgK.

According to the first
law of thermodynamics,
the total energy used in
any process is
conserved.
In an air conditioner, a substance
that easily evaporates and
condenses is used to transfer
energy from a room to the air
outside. When the substance
evaporates,
it absorbs energy as heat
from the surrounding
air.
The Fahrenheit
temperature scale is
defined by what
temperatures?
Water boils at 212
degrees and freezes at
32 degrees.
The energy transferred
between the particles of
two objects because of
the temperature
difference between the
two objects is called
heat
Which of the following
substances is the best
conductor of
transferring energy as
heat?
carbon dioxide gas
Water
iron
rubber
Iron
Radio waves, infrared
radiation, visible light,
ultraviolet rays, and X
rays are forms of
electromagnetic waves
A substance used in
cooling systems that
transfers large amounts
of energy as it changes
state is called a
refrigerant
This is a material
through which energy
can be easily transferred
as heat.
conductor
This is a material that is
a poor energy conductor.
insulator
This is the amount of
energy transferred as
heat that will raise the
temperature of 1 kg of a
substance by 1 K.
Specific heat
This is any device that
transfers energy to a
substance to raise the
temperature of the
substance.
heating system
This is a device that
transfers energy out of
an object to lower its
temperature.
cooling system
This is the energy
transfer as heat between
particles as they collide
within a substance or
between two objects in
contact.
Conduction
This is the temperature
at which an object's
energy is minimal.
Absolute zero
This is a device for
measuring temperature.
