Energy and heat transfer

Question 1

law of conservation of energy

Answer 1

Energy can not be created or destroyed just transformed (under correct circumstances.)

Question 2

Heat

Answer 2

Thermal energy that flows due to a difference in the tempature. heat flows from hot to cold.

Question 3

heat transfer

Answer 3

a method by which heat flows (convection, conduction, and radiation)

Question 4

Conduction

Answer 4

Heat transfer within or between solid objects

Question 5

convection

Answer 5

heat transfer in 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 transfered

Question 8

conductor

Answer 8

A material in 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
