Vocabulary
Stored energy due to the interactions between objects and particles
What is potential energy?
nonrenewable energy source made from splitting the atoms of uranium
What is nuclear energy?
materials that do not allow thermal energy to flow easily through
What are thermal insulators?
Nuclear energy and fossil fuels
What are nonrenewable resources?
the transfer of thermal energy by movement of particles from one part of a material to another
What is convection?
Nonrenewable resources that derive from the remains of ancient plants and animals formed over millions of years.
What are fossil fuels?
Materials that allow thermal energy to move more easily
What are thermal conductors?
Geothermal and hydroelectric energy resources
What are renewable resources?
the transfer of thermal energy by electromagnetic waves
What is radiation?
when the temperature of materials in contact with each other is the same
What is thermal equilibrium?
Both thermal energy and mechanical energy are composed of kinetic and potential energy.
What are the similarities between mechanical energy and thermal energy?
The metal that baking pans are made of
What is an example of a thermal conductor?
the transfer of thermal energy by collisions between particles
What is conduction?
A renewable energy source that comes from thermal energy inside the Earth
What is geothermal energy?
The thermal energy of the water moves into the bottle. Then, the thermal energy moves from the bottle into the air in the fridge.
How does thermal energy move when you place a water bottle in a refrigerator?
This scientific law is the reason we know that all the energy from the fuel used in a car is either used to power the car or it is released to the environment, but never lost.
What is the law of conservation of energy?
States that energy can be transformed from one form to another but it cannot be created or destroyed
What is the law of conservation of energy?
When an energy transformation occurs, some of the energy is always converted into thermal energy.
Why are energy transformations inefficient?
An energy transformation is when energy changes from one form to another; whereas, an energy transfer is when energy is moved from place to place without changing form.
What is the difference between an energy transformation and an energy transfer?
The type of material that coolers should be made of in order to ensure that drinks stay cool longer
What are thermal insulators?
