Used in science to describe large scale processes like the temperature, volume, pressure,and energy of a system characterizing the behavior of a very large number of molecules. The macroscopic values tend to be predictable and represent the average behavior of a system. They give no detailed information about the behavior of individual molecules or units of a system.
Pertaining to aspects of a system which can be measured classically, such as temperature, pressure etc; containing very large numbers of atoms.
a size scale very much larger than that of atoms and molecules, macroscopic systems are governed by classical physics.
