It's a physical change. The water on the plates evaporates to make water vapour, but it is still water, it hasn't changed chemically, it has just changed state from liquid to gas.
this is a chemical change cause you can't return it back to solid salt
Papermaking is not one single unit operation but a series of operations some of them such as pulping and bleaching etc. are chemical change while sheet formation, pressing, drying etc. are physical change.
Wetting: humidification of conditioned air, humidification of clothes during a rain, etc. Drying: deleting water from humid sand, deleting water from humid dishes, etc.
Water is a major component in weathering process. Its essential for all forms of disintegration either Mechanical/Physical, Biological or Chemical. Water aids in physical weathering through alternating wetting and drying of rocks thereby leading to breaking down of the rock. It helps in chemical weathering through dissolution of chemicals in rocks such as limestone. Water is a cause of both chemical and physical weathering.

The drying itself is (always) a physical change.
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.
Physical, it is still H2O
yes
Physical change. The water on the road evaporates, which is a physical change.
Answer: It is a chemical change, 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
i would think physical, unless there is a chemical change occurring..... :)
No new chemical bonds need to be formed or existing chemical bonds broken during drying.
Both
Freeze-drying is a chemical change because it changes the actual composition of the object by removing water.
