Physical, it is simply adding water vapor to the air.
Humidity is water vapor. An increase or decrease in humidity is physical.

Physical change. It is still wax, and can be uncarved by being melted and recast. Chemical changes cannot be undone without applying energy.
Drying (involving only the water evaporation) is a physical change.

It is both. You dry the moisture out of the bread. However, the browning is a chemical change, as the chemical bonds are changed.
It is both- the browning of the crust is a chemical change as well as any other browning. If the filling simply boils and loses moisture ,that is a physical change.
When you say that there is moisture in the air it pretty much means water in the air.It is a physical change, as no new products have been formed.
Chemical broooooooooooooooo niga
it is a chemical change
Chemical I think
You have a phase change which would indicate a physical change since the substance remains the same in composition.
The moisture is just water vapor, so you are getting a phase change from liquid to gas. Phase changes are physical changes. For a vaporizer to produce a chemical change it would have to do something drastic like convert the water in to H2 and O2.
physical as the chemical structure does not change.
