A very common household item these days is a vacuum sealed metal water bottle. These bottles have a thin layer, with no air at all, between the layers of metal. Why does this thin layer of vacuum help keep your drinks cold?(1 point)

Metal is a very bad thermal conductor so the cold stays trapped inside the bottle.

The ice cubes in the drink do not like to touch the metal sides of the bottle and so they tend to stay in the center to keep cool.

The layer of vacuum prevents the heat outside your bottle from conducting through the metal; and so insulates the colder liquid inside.

Metal is a very good thermal insulator and so it prevents the heat outside of the bottle from getting in.
