Sabrina claims that kinetic energy caused the
pinwheel to spin. Which of the following
arguments correctly supports her claim?
The kinetic energy from holding the pinwheel is
transformed into frictional energy as the
pinwheel spins.
The kinetic energy from the blowing air is
captured by the pinwheel and transformed into
mechanical energy as the pinwheel spins.
The kinetic energy from the blowing air is
captured by the pinwheel and transformed into
electrical energy as the pinwheel spins.
The kinetic energy from holding the pinwheel is
transformed into magnetic energy as the
pinwheel spins.
Janica placed an ice cube in her thermos of hot
coffee. Which of the following describes the
change to the energy in the system?
Energy was transferred from the coffee to the ice
cube, but the total energy in the system
remained constant.
Energy was transferred from the ice cube to the
coffee, but the total energy in the system
remained constant.
Energy was transferred from the ice cube to the
coffee, and the total energy in the system
decreased.
Energy was transferred from the coffee to the ice
cube, and the total energy in the system
increased.
What argument does observation C BEST
support?
The lamp was turning electrical energy into light.
Switching the lamp on and off several times in a
row broke the lamp.
The lamp destroyed all of the energy in the
outlet.
The lamp stopped creating electrical energy.
Byrd has a mug of coffee at a temperature of
93°C. He sets the mug on a counter in a room
with an air temperature of 25°C. What is most
likely to happen to the temperature of the
coffee?
The hot coffee will transfer thermal energy into
the air, and the energy transfer will continue until
the coffee is at room temperature.
The air will transfer thermal energy into the
coffee, and the energy transfer will continue until
the coffee is at room temperature.
The hot coffee will transfer thermal energy into
the air and will continue to transfer energy until
they are both 93°C.
The air will transfer thermal energy into the
coffee and will continue to transfer energy until
they are both 93°C.
Why do broken pieces of glacial ice decrease the
temperature of the nearby ocean?
because heat transfers from the ice to the ocean
through conduction
because cold transfers from the ice to the ocean
through convection
because heat transfers from the ocean to the ice
through conduction
because cold transfers from the ocean to the ice
through convection
Iesha says that a ball dropped from a height of
3.0 meters would have less than 96 joules of
kinetic energy when it hits the ground. Is she
correct and why?
She is correct because the higher the ball is
dropped from, the less kinetic energy it will have
when it hits the ground.
She is correct because the higher the ball is
dropped from, the greater kinetic energy it will
have when it hits the ground.
She is incorrect because the higher the ball is
dropped from, the greater kinetic energy it will
have when it hits the ground.
She is incorrect because the higher the ball is
dropped from, the less kinetic energy it will have
when it hits the ground.
What type of energy does a ball have when it
rolls down a hill?
kinetic energy
light energy
magnetic energy
nuclear energy

Decreasing the heat of the burner causes the
balloon to sink and increasing the heat causes
the balloon to rise. How does heat transfer affect
the motion of the air molecules inside of the
balloon?
It causes the cooler air molecules to move faster
and fall via conduction.
It causes the cooler air molecules to move faster
and rise via conduction.
It causes the warmer air molecules to move
faster and fall via convection.
It causes the warmer air molecules to move
faster and rise via convection.
What will happen if the two substances are put
into contact in an isolated system?
The energy in the system will eventually be
destroyed.
The energy in the system will eventually
increase as energy is created.
The energy in the system will transfer from
substance A to B until equilibrium is reached.
The energy in the system will transfer from
substance B to A until equilibrium is reached.
