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.
Summary: 1.A solid is a state of matter that has a definite shape and volume while a liquid is a state of matter that has volume but no definite shape. 2.A liquid takes the shape of the container that holds it while a solid has a shape of its own.
