B
C
D
E
Which example represents a conversion from light energy to electrical energy?
a car
a toaster
a flashlight
solar panels
Which would be best categorized as heat transfer by convection?
Burning your hand by touching a hot stove stop
A heater inside a hot air balloon heats the air and so the air moves upward
Laying out on the beach getting a tan from the sun
A curling iron being used to curl your hair
Katniss Everdeen has to pull back the bow and arrow in order to launch the arrow into her target. Which statement describes the energy of the bow and arrow?
The bow has potential energy when it is being pulled back. As the arrow is released, it transforms into kinetic.
The bow has kinetic energy when it is being pulled back. As the arrow is released, it transforms into potential.
The bow and arrow have no energy until the arrow is released. Then is has kinetic.
Convection occurs within liquids and gases. This is because the particles in solids are:
farther apart and move faster
closer together and don't move at all
closer together and vibrate
closer together and move faster
Based on the diagram of a roller coaster track, what statement is true?
A car at position 1 has more kinetic energy than position 2
A car at position 3 has more kinetic energy than position 1
A car at position 2 has more potential energy than position 1
A car at position 4 has more kinetic energy than position 3
Ella decided to conduct an experiment where she could compare two different plants and their growth. She noticed that Plant 1, with more access to sunlight, grew at a faster rate than Plant 2. Describe the energy transformation that happened in Plant 1.
heat energy to sound energy
radiant energy to heat energy
radiant energy to light energy
radiant energy to chemical energy
If you press down on the spring of these minion toys, the minion will jump up! What form of energy does the spring have as you press down on the minion (before it jumps)?
elastic potential energy
chemical potential energy
mechanical energy
gravitational potential energy
How would you describe the relationship between the mass and energy in this graph?
As the mass increases, the kinetic energy decreases.
As the mass increases, the potential energy increases.
As the mass decreases, the kinetic energy increases.
As the mass increases, the kinetic energy increases.
Sarah turned on a flashlight before leaving her house. As Sarah turned on the flashlight, what energy transformations are taking place?
The chemical energy stored in the battery converts to electrical energy that flows through the wires. The wires turn the flashlight on and energy transforms into radiant and thermal energy.
The chemical energy stored in the battery converts to electrical energy that flows through the wires. The wires turn the flashlight on and energy transforms into radiant.
The chemical energy stored in the battery converts to heat energy. The heat is what lights up the flashlight.
The electrical energy from the battery transforms into chemical energy in the wires.
In the figure, potential energy is being converted into kinetic energy from
3 to 4
1 to 2
2 to 1
4 to 5
Ms. Colwell melted chocolate using a double boiler. She first boiled water by putting water into a pot and heating it on the stove-top. Then she placed another bowl on top of the pot filled with chocolate chips. The chocolate chips melted as the steam from the boiled water rose. Which form of heat transfer occurred in this experiment?
conduction
convection
radiation
combustion
Which type of energy transformation does NOT describe potential energy being changed into kinetic energy?
a book falling off the desk
a roller coaster traveling down a hill
stretching a rubber band
throwing a football
How would the gravitational potential energy of a snowball change if its weight was doubled?
The gravitational potential energy would increase by 10.
The gravitational potential energy would stay the same.
The gravitational potential energy would decrease by half.
The gravitational potential energy would double.
Based on the principles of convection, conduction and thermal radiation, which scenario below is most similar to the following situation?
You holding hand-warmers in your hands to warm them up.
Hot water in a pot rising to the top
Radiation from a microwave heating up food

Point 3
Point 4
The Law of Conservation of Energy states that:
Energy cannot be created or destroyed
Matter cannot be created or destroyed
Energy can disappear
Energy can increase over time
A hot flat iron (straightener) is being used to straighten hair. After using the flat iron, Lisa touched her hair and realized it was also hot. How did the heat travel from the heated iron to the hair?
The molecular movement in the flat iron transferred energy to the molecules in the hair through conduction.
The steam coming from the flat iron traveled to the hair from a distance and made it warm.
Electrons within the rods started moving, distributing heat consistently between the flat iron and hair.
The heat from the flat iron was converted to radiation and light waves traveled to the hair.
Which heat transfer happens through light waves?
conduction
convection
radiation
Which heat transfer happens through physical touch?
conduction
convection
radiation
What energy transformation occurs during photosynthesis?
