Answer:

1. We should eat freshly cut apples because if we leave the apple out after cutting, it begins to turn brownish owing to the oxidation of the key components included in it, and its nutritional value reduces as a result

2. Sublimation is the process by which molecules go directly from solid into the vapor or gas phase.

Deposition is the process by which molecules go directly from the gas phase into the solid phase. Deposition chemistry occurs when molecules settle out of the gas phase and into the solid phase.

Sublimation and deposition are opposite processes. Sublimation is when a substance goes from solid to gas while deposition is when a substance goes from gas to solid.
