Lesson 1
the ability to cause change
energy
states that all of the particles that make up matter are constantly in motion
kinetic theory of matter
is the total kinetic energy of all particles in a substance
thermal energy
is the energy source that can be easily reproduced or replaced by nature
renewable energy
what is the law of conservation of energy
states that energy cannot be created or destroyed. It can only change forms.
is the energy of an object that is due to motion
kinetic energy
is the measure of the average kinetic energy of all the particles in an object
temperature
is the energy transferred from an object at a higher temperature to an object at a lower temperature
heat
is the energy source that cannot be produced, grown, or restored as fast as it is used
nonrenewable energy
in degree celsius, what temperature does water boil?
100 degrees Celsius
is the energy that an object has due to its position, condition, or chemical composition
potential energy
are equally spaced units between two points
degrees
is equal to the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius
calorie
are energy resources made from carbon-rich plant and animal remains
fossil fuels
what is an insulator
is the sum of an object's kinetic energy and potential energy
Mechanical energy
temperature is measured using a....
thermometer
is the transfer of energy as heat from one substance to another through direct contact
conduction
a sedimentary rock formed from the remains of dead plants at the bottom of ancient swamps
coal
what is the transfer of energy by electromagnetic waves
radiation
takes place when energy changes from one form into another form
energy transformation
The scale used most commonly in the United States for measuring temperature
Fahrenheit
is a material that transfers heat very well
conductor
means "rock oil" and it is formed from the remains of single-celled aquatic organisms that lived long ago
petroleum
is nuclear energy renewable or nonrenewable?
nonrenewable
