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.
One property of all matter, whether it's a solid, liquid, or gas, is that it takes up space and has mass. To help you decide if something is a solid, a liquid or a gas, you need to know the properties, (how it looks, acts or feels) of these three states. 3.
