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.
Solid is the. state in which intermolecular attractions keep the molecules in fixed spatial relationships. Liquid is the state in which. intermolecular attractions keep molecules in proximity, but do not keep the molecules in fixed relationships. Gas is that. state in which the molecules are comparatively separated and intermolecular attractions have relatively little effect on their. respective motions.
