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)

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.

Explanation:

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.

The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration  for bromine with atomic number of 35 and thus containing 35 electrons is:

The nearest noble gas is Argon with 18 electrons and thus electronic configuration  for bromine in terms of noble gas is:
