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.
*Water is one of the few substances that are less dense as a solid than as a liquid. While most substances contract when they solidify, water expands. This property is due to the hydrogen bonding. When water is above 4 Â°C it behaves like other liquids; it expands as it warms and contracts when it cools.
