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.
qualitative differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the. state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter. expands to occupy whatever volume is available.
