energy and heat transfer

Question 1

law of conservation of energy

Answer 1

energy can’t be destroyed or created just transformed.

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

a method by which heat flows.

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 (electric, thermal, or sound) cannot be easily transferred.

Question 8

temperature

Answer 8

the measure of the average speed of all particles.

Question 8

conductor

Answer 8

a material through which energy (electric, thermal, or sound) can be easily transferred.

Question 9

thermal energy

Answer 9
