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 physical process.
Freeze-drying is a chemical change because it changes the actual composition of the object by removing water.
No, it is only a physical change since the chemical properties of alcohol do not change.
Physical!Ice is H20(s) and Water is H2O(l)
It is a physical property.
Physical property the physical state of the water is changed from ice to water not the chemical state i.e it is still h2o
yes
Freeze-drying is a chemical change because it changes the actual composition of the object by removing water.
i would think physical, unless there is a chemical change occurring..... :)
Freezing is a physical change.

no as it can be turned back to water or be freeze to ice by over cooling.
Physical change: it's just beginning to freeze. Also, it's chemical composition stays the same.
physical
milk going sour is a chemical change because it can't be reversed. Most physical changes can be reversed for example snow melting is a physical change because it can freeze again.
No not ia any way
it's physical change
