No, this is only a phase change albeit a complex one.
Answer: It is a chemical change, it changes the actual composition of the object by removing water.
Freeze-drying is a chemical change because it changes the actual composition of the object by removing water.
It is a chemical change. Fermentation causes bonds to break within a compound and new bonds form thus chemically changing the initial 'reactant'.
Does the water ever change into anything except water? No, so it's not a chemical 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.
Physical, it is still H2O
Drying (involving only the water evaporation) is a physical 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.
Answer: It is a chemical change, it changes the actual composition of the object by removing water.
Physical change. The water on the road evaporates, which is a physical change.
Freeze-drying is a chemical change because it changes the actual composition of the object by removing water.
It is a Physical Change because i dont know but im sure that is a physical change :P
Drying clothes involves a physical change rather than a chemical change. The water present in the wet clothes evaporates when exposed to heat or air, changing its state from liquid to gas without undergoing a chemical reaction.
It is a chemical change. Fermentation causes bonds to break within a compound and new bonds form thus chemically changing the initial 'reactant'.
Does the water ever change into anything except water? No, so it's not a 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.
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.
