Question | Answer |
---|---|
The ability to do work | Energy |
The form of energy associated with the reactions in the sun. | Nucear |
The form of energy associated with visible light, heat and radio waves. | Electromagnetic |
The form of energy associated with current of electrically charged particles. | Electric |
The form of energy associated with the energy stored in the chemical bonds in food. | Chemical |
Kinetic energy depends on mass and | Velocity |
Which factor in the kinetic energy equation has the MOST effect on the KE? | Velocity |
KE is measured in | Joules |
Work is the transfer of | Energy |
KE is the energy of | Motion |
Potential energy depends on weight and | height |
Gravitational potential energy depends on mass, height and | Gravity |
PE is measured in | Joules |
Velocity is measured in | meters per second |
Weight is measured in | Newtons |
The type of energy associated with particles in motion | Thermal energy |
Any form of energy can be converted into any | Other form |
A change from one form of energy to another is called a(n) | Energy conversion |
An energy conversion is the same as an energy | Transformation |
Tossing an orange up and down is an example of an energy conversion between | KE and PE |
Where is potential energy the greatest in a pendulum swing? | At the top of the swing |
Where is the kinetic energy the greatest when tossing a ball up and down? | Just before it hits your hand or leaves your hand. |
The law of conservation of energy says that you cannot create or ____________ energy. | Destroy |
A pendulum eventually stops, not because it LOSES energy, but because some of the energy is converted into heat by this process. | Friction |
The rate at which work is done or energy is transferred is called. | Power |
Consumer's Energy charges its customers by this unit. | KWh (kilowatt hour) |
The measure of the average kinetic energy of a substance's particles | Temperature |
Temperature scale used by the USA | Fahrenheit |
Temperature scale used by most of the world | Celsius |
Temperature scale used by physical scientists | Kelvin |
Temperature at which water boils on the Celsius scale | 100 degrees |
Absolute zero in celsius | -273 degrees |
Temperature at which water freezes on the Fahrenheit scale | 32 degrees |
The temperature at which no more energy can be removed from the particles of a substance is called | absolute zero |
The measure of the kinetic energy of a substance's particles | Thermal Energy |
The movement of thermal energy from an area of warm to cool | Heat |
Heat always moves in this direction | Warm to cool |
The transfer of heat through empty space is | Radiation |
The transfer of heat through gases or liquids in circular currents | Convection |
The transfer of heat through the contact of two substances | Conduction |
An object that allows heat to transfer through very easily | Conductor |
An object that does not allow heat to transfer through easily | Insulator |
Which has more thermal energy? A 500 ml container of boiling water or a 50 ml container of boiling water? | 500 ml |
Which type of heat transfer are you experiencing when you lay out in the sun? | Radiation |
Which type of heat transfer are you experiencing when you burn your hand on a hot spoon? | Conduction |
What kind of heat transfer are you experiencing when you heat up your home with a furnace? | Convection |
When enough thermal energy is added or removed, this may occur | Change of state |
This state of matter has particles that are packed together with the least amount of energy. | Solid |
This state of matter's particles move the fastest of any other state. | Gas |
This state of matter's particles can fill the shape of its container. | Gas or liquid |
When a solid changes to a liquid | Melting |
When gas changes to a liquid | Condensation |
When a liquid changes to a gas from the SURFACE of a liquid | Evaporation |
When vaporization occurs in a liquid | Boiling |
The melting point is the same as the | Freezing point |
The vaporization point is the same as the | Condensation point |
During a change of state, this is either increasing or decreasing. | Thermal energy |
During a change of state, this stays the same | Temperature |
