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.
2005. 13.3 The Nature of Liquids Particle Spacing Intermolecular attractions reduce the amount of space between particles in a liquid. Particle Motion Particles in a liquid have enough kinetic energy to flow The tendency for particles move and their attraction for one another account for the physical properties of liquids The Nature of Liquids Viscosity Viscosity is a measure of the resistance of a liquid to flow.
