Explain why changes of state are considered physical transitions and not chemical processes?
This is because when a substance, such as water, is changed to a solid (ice) it keeps its same, original properties! A chemical change involves changing the substance into a completely new substance. Water, on the other hand, can go from a solid, to a liquid, to a gas without changing its properties, only its state!
What else can I help you with?
Is processes a physical or chemical property?
Processes typically refer to actions or steps that occur in a system or in a series of events, rather than a specific property like physical or chemical. These actions can be driven by physical or chemical properties, but the processes themselves are not properties.
Can chemical change and physical change happen simultaneously?
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.
Is a soluble in alcohol a physical or chemical property?
Solubility is considered as a chemical property.
Is heating of ammonium chloride in a test tube a physical or chemical change?
This is a chemical change (thermal decomposition).
Is freezing nitrogen gas a chemical change?
No, freezing nitrogen gas does not involve a chemical change. It is a physical change where the nitrogen gas transitions from a gaseous state to a solid state without any chemical reactions taking place.
Who was the first scientist who discovered chemical and physical processes?
Unknown; the knowledge of the chemical and physical processes are very old.

What does chemical and physical processes include?
Physical processes: melting, boiling, grinding, sieving, vaporization, deposition, etc. Chemical processes: polymerization, oxidation, reduction, chemical reactions, thermal degradation, dissociation, etc.
Is evaporation a chemical property or a physical property?
Evaporation is a physical property. It is the process by which a substance transitions from a liquid state to a gaseous state without undergoing a chemical change.
What is energy is thought of as garbage?
Thermal energy is often considered useful because it is the "waste product" of many chemical and physical processes.

Is digesting a candy bar a physical or a chemical process?
Digesting a candy bar involves both physical and chemical processes. Physical processes include chewing and breaking down the food into smaller pieces, while chemical processes involve enzymes breaking down the food into smaller molecules that can be absorbed by the body.
Are pop cans a physical or chemical change?
Pop cans are produced by physical processes.
Is evaporation considered a chemical or physical change?
Evaporation is considered to be a physical change. The chemical nature and identity of the evaporated material is the SAME as that of the liquid.
Can anyone summarise the physical processes long answers needed please?
Physical processes is changes that can be seen from the eye. These changes affecting the form of a chemical substance but does not change its chemical composition.
Is rotting a physical change?
Rotting is a chemical change, as it involves the decomposition of organic matter through biological or chemical processes. It results in the formation of new substances, such as gases and compounds, rather than just a rearrangement of the original materials.
Is exothermic a physical or a chemical change?
It can be either. Some exothermic processes, such as combustion, are chemical changes while others, such as condensation, are physical.
