This isn't a proper question, but I will do my best to answer.
When matter changes from one phase to another it is called...
Solid >>> Liquid = Melting
Liquid >>> Solid = Freezing
Gas >>> Liquid = Condensation
Liquid >>> Gas = Vaporization
These are less common:
Solid >>> Gas = Sublimation
Gas >>> Solid = Deposition
Gas >>> Plasma = Ionization
Plasma >>> Gas = Deionization
No, chemical changes and physical changes are distinct processes that occur separately in a system. Chemical changes involve the formation of new substances with different chemical properties, while physical changes involve alterations in the state or appearance of a substance without changing its chemical composition. These processes do not typically occur simultaneously.
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
This could refer to a chemical transformation (chemical change), a chemical reaction, or spontaneous change. Some changes require another substance or substances to be mixed together. Some reactions will occur by themselves without any outside manipulation or stimulation.
The physical and chemical changes that occur in a system are alike because they change the state of the reactants. They are different because a chemical change produces a new substance while a physical change does not produce any new substance.Differ in physical:1. A difference in the appearance, smell, or simple display of a sample of matter without a change in composition.2. Be observed without changing the identity of the substance3. Can be seen or measured without changing a material.Differ in Chemical:1. There is a change of the substances in question2. determines how a substance changes into a completely different substance.3. Tells how the substance forms new substances when it mixes with something else.
Chemical changes occur when the elements, their valences, and their amounts change. 4H + O2 => 2H2O is a chemical change because the valences change from unfilled to shared. Physical changes occur when the material phase changes. In fact, in 4H + O2 => 2H2O we also have a physical change...from gas to liquid water (in most cases). NOTE: That there was a chemical change here is incidental, the phase change is the physical change.
Chemical Change.

After a chemical reaction new compouds (called also products) are formed.
A substance's chemical composition, which is determined by the types and arrangement of its atoms, always remains the same regardless of physical or chemical changes that may occur.
The difference between a chemical property and a chemical change is that the change is how the property of the chemical changes when it undergoes a chemical reaction.
When physical changes occur in matter, the substance's state or appearance changes without altering its chemical composition. In contrast, chemical changes involve a modification in the substance's chemical composition, resulting in the formation of new substances.
A chemical reaction occur.
Any chemical change occur.
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
This change in the state of matter (liquid to solid) is called freezing, not melting; it is a physical change, the chemical nature of the molecules is not changed.
Flammability is a chemical property because when you burn something there is a chemical reaction, therefore a chemical change will occur.
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
