Heat Transfer Vocabulary

Question 1

Law of Conservation of Energy

Answer 1

Energy cannot be created or destroyed just transferred (under normal conditions)

Question 2

Heat

Answer 2

Thermal Energy that flows due to a difference in temp. Heat flows from hot to cold

Question 3

Heat transfer

Answer 3

A method by which heat flows
(conduction, convection, radiation).

Question 4

Conduction

Answer 4

Heat transfer within or between solid objects.
(they are in contact)

Question 5

Convection

Answer 5

Heat transfer into or out of fluids
(air or water)

Question 6

Radiation

Answer 6

Heat transfer due to packets of energy called photons that can travel through many substances, even empty space. (this is how we get things from the sun)

Question 7

Insulator

Answer 7

A material through which energy (electrical, thermal, or sound) cannot be easily transferred. ( An oven mitt)

Question 8

Conductor

Answer 8

A material through which energy (electrical, thermal, or sound) can be easily transferred. (Anything metal)

Question 9

Temperature

Answer 9

The measure of the average speed of all particles. (how fast it is moving, if temp is high there moving fast if temp is low they move slow.)

Question 10

Thermal Energy

Answer 10

The total energy of all particles in an object.
