The study of fluid dynamics in physics is determined by the properties of an ideal fluid.
State the common phases of matter.
Explain the physical characteristics of solids, liquids, and gases.
Use the PhET simulation to complete the table below. Determine the shape, flow, volume stability and compressibility of solids, liquids and gases.
Describe the arrangement of atoms in solids, liquids, and gases.
Distinguishing properties of solids, liquids, and gases arise from the varying interactions between atoms and molecules.
This program defines the three states of matter, and illustrates the lattice-work pattern of molecules in solids. Viewers learn the origin of the word "molecule."
Video: eureka 16 solidsAs molecules in a solid get hotter, they vibrate faster and faster and eventually slip out of their lattice-work pattern. When this occurs, the substance melts, changing from a solid to a liquid state.

A fluid is a liquid, gas, or other material that:
continuously deforms (flows) under an applied shear stress, or external force (no fixed shape)
is incompressible and has no viscosity
