Answer:
Minimizes heat transfer
Explanation:
To keep my lunch from getting cold at the beach, a material the minimizes heat transfer will be the most desirable.
- Such material should be modified to prevent had transfer by convection, conduction and radiation.
- This kind of material is desirable because heat generally flows from a place of high amount to that of low amount.
- Since the food will mostly have a temperature higher than the ambient one, it is expected that heat will flow away from the food to the environment.
- This will make the food cold.
- If such heat transfer is prevented, then, the food will remain hot.
