Q

Convection

A

Heat is transferred by the movement of currents within a fluid. This current, called a convection current, moves in a circular motion caused by the rising of heated fluid/air and the sinking of cooler fluid/air

17
Q

Radiation

A

The transfer of energy by electromagnetic waves

18
Q

Conductor

A

Transfers thermal energy well

19
Q

Insulator

A

Does not transfer thermal energy well

20
Q

Joules

A

Unit of measurement for energy

21
Q

Sound Energy

A

Kinetic energy caused by the vibration of particles in a medium such as steel, water ,or air

22
Q

Energy Transformation

A

Occurs when energy changes from one form to another form

23
Q

Law of Conservation of Energy

A

States that energy cannot be created or destroyed but can change forms

24
Q

Kinetic Theory of Matter

A

States that all of the particles that make up matter are constantly in motion

25
Q

Degrees

A

Equally spaced units between two points

26
Q

Thermometer

A

Instrument used to measure temperature

27
Q

Calorie

A

A way to measure heat. One calorie is equal to the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius

28
