Energy & Heat Transfer

Question 1

Law of conservation of energy

Answer 1

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

Question 2

Heat

Answer 2

Thermal energy that flows due to a difference in temperature. 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.

Question 5

Convection

Answer 5

Heat transfer into or out of fluids.

Question 6

Radiation

Answer 6

Heat transfer due to packets of energy called photons that can travel through many substances, even empty space.

Question 7

Insulator

Answer 7

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

Question 8

Conductor

Answer 8

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

Question 9

Temperature

Answer 9

The measure of the average speed of particles.

Question 10

Thermal Energy

Answer 10
