heat dw i'n iawn mae'n iawn dw i'n iawn mae'n iawn--

Question 1

heat

Answer 1

energy transfer ‘hot’ –> ‘cooler’

Question 2

objects contain heat

Answer 2

no, thermal energy

Question 3

temp

Answer 3

av kinetic energy particle in substance

Question 4

heat vs temp

Answer 4

heat energy transit temp sum of all internal energy (this and kinetic energy particles)

Question 5

heat movement connexion

Answer 5

as object loses energy (heat) less kinetic

Question 6

heat transfer

Answer 6

exchange thermal between physical systems where energy transferred hot to cool

Question 7

conduction

Answer 7

transfer heat direct contact

Question 8

convection

Answer 8

transfer heat convection current air/water

Question 9

radiation

Answer 9

transfer electromagnetic waves

Question 10

how conduction

Answer 10

energy between molecules direct contact when hit

Question 11

how convection

Answer 11

fluids/air heated, particles move rapid expands less dense rises to top cools become dense sinks repeat

Question 12

how radiation

Answer 12

heat moves as energy waves hit cooler molecules move faster more energy hotter
