Energy and heat Transfer

Question 1

law of conservation

Answer 1

energy can not be created to destroy just transformed( under normal condition)

Question 2

Heat

Answer 2

the thermal energy that flows due to a difference in temperature. heat flows from hot to cold

Question 3

heat transfer

Answer 3

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 fuluids

Question 6

radiation

Answer 6

heat transfer due to packets of energy called photons that can travel through many substances, even empty spaces

Question 7

insulator

Answer 7

a material in 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 transformed.

Question 9

temperature

Answer 9

The measure of the average speed of all particles

Question 10

thermal energy

Answer 10

The total energy of all particles in an object
