Since liquids when expanding will generate some force, and the liquid cannot compress, it would be dangerous to not allow some ullage space in the container above the liquid. Some gas above the liquid can easily compress, and absorb the (thermal) expansion of the liquid.
The ullage is the empty space in a closed bottle. So in a bottle of water, the ullage is between the surface of the water and the bottom of the bottle cap.
What is an ullage report
Ullage is the empty space in the tank.
Ullage refers to the space between the level of the wine and the top of the bottle. It tends to increase with age.
There is no such thing. Water cannot be manufactured, it can only be collected, treated, packaged and transported.

Ullage is the empty space in a container. This usually refers to a gas or oil storage container. An ullage report states the difference between the height of the cargo and the roof of the container.

It is called ullage
"Ullage" is an old word used in transportation of liquids. It specifically means the amount of liquid within a container that is lost, as by leakage, during shipment or storage.
The shortfall in volume of liquid in a cask or bottle is often referred to as ullage. It is the difference between the actual volume of liquid and the full capacity of the container. Ullage can occur due to evaporation, leakage, or other factors during storage or transportation.
Ullage measures the empty space in a container, such as a tank or barrel, that is not filled with liquid. It is often used in the context of wine or spirit barrels to denote the amount of air above the liquid, which can impact quality and aging. In shipping and storage, ullage is important for assessing the volume of product available and ensuring safety during transport.
