deeper small necked containers allow less evaporation, shallow wide necked containers (bowl shaped) allow more evaporation.

As a liquid evaporates, vapor pressure increases, pushing it in the direction of any opening in the container. If the shape of the container widens away from the liquid, the vapor pressure will decrease, allowing faster evaporation. If the shape of the container narrows, it can restrict the flow of the vapor, reducing the rate of evaporation. But in an open container, these effects are not as critical as the relative size of the opening(s). A narrow necked bottle will allow much less evaporation than an open bowl.

The larger the surface area, the greater the amount of evaporation. A container with a small diameter would not have much surface area and there could not be very much evaporation.

Evaporation is excitation of molecules away for the surface of a liquid. The molecules become energised into a gas state.
Therefore whichever container gives the greatest surface area will have the greatest evaporation.

A container which gives large liquid surface area and sides which do not restrict air flows or contain the water vapour will give best evaporation.

The larger the surface - the faster the evaporation- the more is exposed to air- D

Put a litre of water in a wide, flat container then put a litre of water in a tall narrow container, the water in the wide, flat container will evapourate quicker because it has a higher surface area exposed to the air.
