Yes, because the chemical composition remains unchanged. Water is still H2O whether it is solid, liquid or a vapour.
no, because the wood isn't changing itself, you are changing the wood.
it is a physical change
Melting is a physical change because it does not involve a change in the chemical composition of the substance. When a substance melts, its molecules or atoms move apart, resulting in a change in its physical state from solid to liquid.
it is a physical change because it is not making a new substance. It is just changing the size/shape
The evaporation of water in a lake is a physical change. This is because the water is changing state from liquid to gas without any change in its chemical composition.
Tearing is a physical change as it alters the physical appearance of an object without changing its chemical composition. A change of state, on the other hand, refers to a transition from one state of matter (solid, liquid, gas) to another.
Yes, it is a physical change. For if it was a chemical change, it would not be able to change back; but when you are just changing the state of the item/substance it can be changed back.

No, a liquid changing to a gas is a change of state or a physical change.
No, a liquid changing to a gas is a change of state or a physical change.
Well obviously, a physical change and a chemical change both envolve changing of state
Physical change.
Changing state is a physical change. The chemical composition of the substance doesn't change, only the form the substance takes. Liquid water changing to ice is still water-- the chemical composition hasn't changed. An example of chemical change would be methane (CH3) burning in oxygen (O2) to form carbon dioxide (CO2) and water vapor (H2O). The methane and oxygen no longer exist as themselves but have become carbon dioxide and water vapor-- their chemical compositions have changed.
Changing shirts is a physical change.
no, because the wood isn't changing itself, you are changing the wood.
No, changes of state such as this are physical changes.
You are changing the state of the fruit but not its properties or composition.
