Name the process involved in the following :

1) an acetone bottle is left open and the bottle becomes empty

2) a drop of ink placed on the surface of water contained in a glass spreads throughout the water.

1) Sublimation

2) Diffusion

1. The answer is sublimation because acetone is a volatile liquid and it absorbs heat from the surrounding and turns directly to gas without boiling .
2. The second answer is diffusion because water and ink both are fluids and both have inter molecular space so they get randomly diffuse into one another.
