A significant part of aeronautical science is a branch of dynamics called aerodynamics, which deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft.
When you pour a liquid from one container to another, the liquid takes the shape of the container. The volume of the liquid is the same. The properties that solids and liquids share are that they both have definite volume.
Solids, liquids, gases All materials which you see around you are either solids, liquids or gases. Solids canbe recognised because they are firm and keep their own shape. We can explain whatwe mean by this using the example of water. Ice is solid water.
