Difference between Microscopic and Macroscopic Physics – Class 11 | Chapter – 1 | Physics Short Notes Series PDF for NEET & JEE

Microscopic and Macroscopic Physics: Microscopic physics refers to the study of physical phenomena at the scale of individual atoms and molecules, as well as subatomic particles such as electrons and protons. It is a branch of physics that seeks to understand the behavior of matter and energy at the smallest scales, and to uncover the underlying laws that govern the interactions between individual particles.

Macroscopic physics, also known as classical physics, is the study of physical phenomena that are visible to the naked eye and can be measured and described using macroscopic (i.e., large-scale) concepts and theories. It deals with the behavior of large collections of particles, such as gases, liquids, and solids, and encompasses a wide range of physical phenomena, from the motion of objects to the behavior of fluids and the properties of materials.

Difference between Microscopic and Macroscopic Physics

Parameters of Comparison Macroscopic Microscopic
Definition The macroscopic term is associated with the bulk properties of substances. The microscopic term is associated with the properties of the constituents of the matter.
Visibility The changes in macroscopic properties are visible to the naked eye. The changes in microscopic properties are not visible to the naked eye.
Significance Macroscopic properties are concerned with the overall behavior of the system. Microscopic properties are concerned with the very fundamental structure of the matter.
Measurements Macroscopic properties have big units of measurement such as kilogram, liter, gram/liter, etc. Microscopic properties have small units of measurement such as micrometer, milligram, angstrom, etc.
Thermodynamics Macroscopic properties are used for studying classical thermodynamics. Microscopic properties are used for studying statistical thermodynamics.
Example Some examples are pressure, temperature, and volume. Atomicity, chemical bonding, hydrogen bonding, intermolecular forces, etc.
