matte black

Question 3

What are the steps of the emission practical?

Answer 3

fill Leila’s cube with hot water

point infared dectector at each surface to see how much infared is emitted.

keep same distance between infared detector and leila’s cube ( makes measurements repetable)

Question 4

Which surface emitts the most to least infared?

Answer 4

most—-least

matte black
shiny black
white
shiny metallic

Question 5
