Why should any body accept that order & disorder are different quanties?

Question

It is manifestation of our pchycology. As a physical quantity there is no difference.Both are different possibilties of arrangemnt of units


Example:- Drop a glass it breaks to small pieces, even broken pieces, may look like some from of design for some people. So order & disorder not necessarily different states. It is how we look at it & how much benfit they give us



Now Look at Super nova to be a disorder & formation of planets & next genaration star from supernova to be order. we all know that supernova & formation of planets is frequent phenomena. Now if order & disorder are physcical quantities than genaraly order does not come from disorder it more often incerases with time. How is this ?
So I think order & disorder or not physical quantites which can be calculated. there are our perceptions depending on how we look at them

Answer 1

The concept of entropy (Greek: εν (en=inside) + verb: τρέπω (trepo= to chase, escape, rotate, turn)) in thermodynamics is central to the second law of thermodynamics, which deals with physical processes and whether they occur spontaneously. Spontaneous changes occur with an increase in entropy. Spontaneous changes tend to smooth out differences in temperature, pressure, density, and chemical potential that may exist in a system, and entropy is thus a measure of how far this smoothing-out process has progressed. In contrast, the first law of thermodynamics deals with the concept of energy, which is conserved. Entropy change has often been defined as a change to a more disordered state at a molecular level. In recent years, entropy has been interpreted in terms of the "dispersal" of energy. Entropy is an extensive state function that accounts for the effects of irreversibility in thermodynamic systems.

Quantitatively, entropy, symbolized by S, is defined by the differential quantity dS = δQ / T, where δQ is the amount of heat absorbed in an isothermal and reversible process in which the system goes from one state to another, and T is the absolute temperature at which the process is occurring.[3] Entropy is one of the factors that determines the free energy of the system.

This thermodynamic definition of entropy is only valid for a system in equilibrium (because temperature is defined only for a system in equilibrium), while the statistical definition of entropy (see below) applies to any system. Thus the statistical definition is usually considered the fundamental definition of entropy.

Answer 2

The glass is an illustration of order to disorder.
The super nova is the opposite.
The disorder of a super nova is super disorder but from that disorder come the order of a solar system.
The universe seems to be an increasing disorder but the universe cannot be in a chaotic state when it goes out of existence.

Answer 3

Order and disorder are time event sequences within a given system. Order and disorder are relative to the viewers direction in time as well as philsophical opinion.

Answer 4

They're just two words to descrive the way we percieve arrangements of things. They are not physical quantities with a value assigned to them.

Answer 5

I don't think this is going to pay the bills....
