Energy cannot be created or destroyed only transformed. The amount of energy in a closed system is always the same
What is the LAW OF CONSERVATION OF ENERGY
100
All particles that make up matter are constantly in motion.
What is the KINETIC THEORY OF MATTER
100
Adding energy to an object in the form of heat may result in a change of___
What is STATE
Adding heat to ice->water
Adding heat to water ->water vapor
100
An energy source that can be wasily reproduced or replaced by nature
What is a RENEWABLE ENERGY RESOURCE
100
The ability to do work
What is ENERGY
200
amount of work an object can do based on its energy of motion plus its energy based on position, shape, or condition.
What is MECHANICAL ENERGY
Mechanical Energy=KE + PE
200
The theoretical temperature at which all particle motion stops.
What is ABSOLUTE ZERO.
200
Heat always flows from___to____
The object at a higher temperature to the object at a lower temperature. HOT TO COLD.
200
an energy source that cannot be produced, grown, or restored as fast as it is used.
What is a NONRENEWABLE ENERGY RESOURCE
200
A measure of the average kinetic energy of all the particles in an object
What is TEMPERATURE
300
What 6 forms can energy take?
What are Sound energy, electromagnetic energy, electrical energy, chemical energy, thermal energy, nuclear energy
300
Explain particle motion of solids, liquids and gasses.
Solid-vibrate slightly, close together-slow
Liquid-move more freely, slip around each other-faster
Gas-far apart, particles collide with one another -high speeds
300
If two objects are at the same temperature the on with (more, fewer, or the same amount of) particles will have a higher thermal energy.
Choose one.
What is MORE
An ocean has more thermal energy than a glass of water at the same temp. because it has more molecules
300
What is a fossil fuel and list the three fossil fuels used today.
-energy resource made from carbon-rich plant and animal remains
Coal, Natural Gas, Petroleum (oil)
300
The energy transferred from an object at a higher temperature to an object at a lower temperature
What is HEAT
400
What is an energy transformation and give an example.
When energy changes from one form into another form
If you rub your hands together you hear a sound, and your hands get warm this is mechanical energy being changed into both sound and heat energy
400
Celsius, Fahrenheit, Kelvin
What are the THREE COMMON TEMPERATURE SCALES
400
The total kinetic energy due to the movement of the particles that make up the object.
Energy resources made from carbon-rich plant and animal remains.
What are FOSSIL FUELS
500
How can an object have both potential and kinetic energy?
A flying bird has kinetic energy because of its speed or growing speed, and potential energy because of its height from the ground
Kinetic energy due to movement and potential due to positioning.
500
Describe the relationship between temperature and kinetic energy.
The higher the temp. the faster the particles move so the higher the kinetic energy. The lower the temp. the lower the KE.
500
What are the three ways to transfer energy as heat and explain
What are CONDUCTION-transfer by direct contact,
CONVECTION- transfer by movement of a liquid or gas , and RADIATION- transfer through electromagnetic waves
500
Give one example of where geothermal energy is used
Ex:
Mount Vernon Presbyterian School
500
All particles that make up matter are constantly in motion
