Why is it not vital to keep the lid of a chest freezer closed?
Any freezer needs to be kept closed as much as possible if you wish for it to remain cold. However a chest freezer will not warm up as fast as an upright freezer. This is because the cold air in the freezer is heavier than the air outside of the freezer. When you open an upright freezer the cold air "falls" out, this can't happen with a chest freezer.
