5. To keep your lunch cold at the beach, would you want a material
that minimizes heat transfer or maximizes heat transfer? Explain (keep it short please)

Respuesta :

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.
