Rate Of Heat Transfer

Question 1

Smaller volume

Answer 1

Will cool more quickly

Question 2

5 factors affecting rate of heat transfer

Answer 2

1. Volume
2. Surface area
3. type of material
4. Whether it is a insulator/conductor
5. Whether it is in contact with a insulator/conductor

Question 3

What does a vacuum stop

Answer 3

All conduction and convection

Question 4

What does a shiny surface minimise

Answer 4

Heat loss by radiation

Question 5

What does insulating foam minimise

Answer 5

Conduction

Question 6

Plastic filled with cork/foam minimises what?

Answer 6

Heat through conduction

Question 7

Bigger Surface area

Answer 7

More infrared waves emitted/absorbed at any one time so quicker transfer of heat
