conduction

Question 1

what is thermal conduction?

Answer 1

the process where heat is transferred by collisions between neighbouring atoms or molecules

Question 2

what does a high thermal conductivity mean?

Answer 2

that it is a good conductor

Question 3

what does a low thermal conductivity mean?

Answer 3

that it is a bad conductor/ a good insulator

Question 4

what is a conductor?

Answer 4

anything that allows electricity or heat to flow through it eg. metals, especially copper

Question 5

what is an insulator?

Answer 5

anything that doesn’t allow electricity or heat to flow it eg. plastic, wood, glass, rubber

Question 6

how to test the thermal conductivity of metals?

Answer 6

the drawing pin experiment: drawing pin coated in vaseline attached to the end of a metal rod which is being heated. first to fall: high thermal conductivity.

Question 7

how can you prevent heat being transferred by conduction?

Answer 7

make a vacuum

Question 8

what materials can heat be transferred to by conduction?

Answer 8

solids and liquids because the particles are closer together in them
