Is freeze drying physical change or chemical?
Answer: It is a chemical change, it changes the actual composition of the object by removing water.
Is a grape drying in the sun a chemical or physical change?
It is a chemical change. Fermentation causes bonds to break within a compound and new bonds form thus chemically changing the initial 'reactant'.
Is drying of fevicol a chemical change or a physical change?
Drying of fevicol is a chemical change obviously !! Its because we cannot bring back the original properties of fevicol whatsoever we do to it !!! ---------------------------------------------------- But evaporation of solvents is a physical process.
Is paint drying on a fence a chemical reaction?
Yes, paint drying on a fence involves a chemical reaction. When paint is applied, solvents evaporate, and the remaining components, such as polymers and pigments, undergo a curing process that leads to solidification. This process can involve oxidation and cross-linking of the paint's chemical components, transforming the liquid paint into a solid film. Thus, the drying of paint is a result of both physical and chemical changes.
What processes is not a physical change drying wet clothes cutting snowflakes out of paper light a match from a matchbook?
Ignition of a match is a chemical process.
Is the drying of wet laundry a chemical reaction?
No, it is a physical process - water evaporation.
Is drying of fish is a chemical change?
No, drying of fish is a physical change, not a chemical change. The process of drying simply involves the removal of water from the fish, causing it to undergo a physical transformation, but its chemical composition remains the same.
Is drying fish physical change?
Drying (involving only the water evaporation) is a physical change.
Is freeze drying physical change or chemical?
Answer: It is a chemical change, it changes the actual composition of the object by removing water.
Is drying hair a chemical or physical?
The drying itself is (always) a physical change.
Is spilled gasoline drying a chemical or physical change?
Gasoline evaporation is a physical process.
Does drying wood in a shed result in chemical change?
Drying wood in a shed does not result in a chemical change because the process involves the removal of water through evaporation, which is a physical change. The structure and composition of the wood remain the same.
Is quick drying a chemical or physical properties?
Quick drying is a physical property, meaning it is related to the behavior of a substance based on its physical attributes and interactions, rather than a chemical change. Materials that dry quickly typically have high surface area to volume ratios, allowing for rapid evaporation of moisture.
What process is not a physical change drying wet cloths cutting snowflakes out of paper lighting a match from a matchbook?
Ignition of a match is a chemical process.
How can a hydrate be turned into an anhydrate?
By drying, heating, vacuum drying
Is a grape drying in the sun a chemical or physical change?
