Document Summary
Liquids (water, oil, etc. : molecules are spaced farther apart, the intermolecular forces are smaller than for solids, molecules have more freedom of movement, can be easily deformed but not easily compressed. Gases (air, oxygen, etc. : are easily deformed and compressed, have an even greater molecular spacing and freedom of motion with negligible cohesive intermolecular forces. The study of these materials is called rheology. Fluid characteristics can be described qualitatively in terms of certain basic quantities such as length, time, and mass. Qualitative: serves to identify the nature, type, or characteristics (length, time, stress, and velocity) Quantitative: requires both a number and a standard by which various quantities can be compared. On the first page is a list of some dimensions for a number of common physical quantities. All theoretically derived equations are dimension homogeneous, meaning the dimensions on the left side of the equation must be equal to the right side.
