Question

Aluminum foil has a shiny side and a dull side. Many experts believe that the shiny side of the aluminum foil should face the food when you are using it to cover the food. What process would explain the reason why the shiny side should face the food?

A) conduction.
B) convection.
C) insulation.
D) radiation.

Answer 1

it's D

Step-by-step explanation:

this is because the shine side is more reflective

Answer 2

Answer: Option d: radiation.

Explanation: The shiny side has a bigger reflective coefficient, so the heat radiated by the food can be reflected in it and stay inside the foil, which makes the temperature to increase faster and keeps it more consistent, and if it would face the other side, it will reflect some radiated heat and it will never reach the actual food, so the correct answer is option d.
