The sign ΔS sys for process that pond freezes in winter has to be determined. Concept introduction: Entropy change: The sign of ΔS o for a reaction is determined by using the following rules: When a molecule is broken down and gives two or more smaller molecules. When the moles of gas is increases (by the breaking of molecules) Solid changes to liquid or gas state or liquid state changes to gas state. Entropy ( S ) : it is used to describe the disorder. It is the amount of arrangements possible in a system at a particular state. If the disorder increases in a system, then Δ S > 0 positive If the disorder decreases in a system, then Δ S < 0 negative If the disorder equal in a system, then Δ S = 0

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Interpretation Introduction
Interpretation:
The sign ΔSsys for process that pond freezes in winter has to be determined.
Concept introduction:
Entropy change:
The sign of ΔSo for a reaction is determined by using the following rules:
When a molecule is broken down and gives two or more smaller molecules.
When the moles of gas is increases (by the breaking of molecules)
Solid changes to liquid or gas state or liquid state changes to gas state.
Entropy(S): it is used to describe the disorder. It is the amount of arrangements possible in a system at a particular state.
If the disorder increases in a system, then ΔS>0 positive
If the disorder decreases in a system, then ΔS<0 negative
If the disorder equal in a system, then ΔS=0
