You will know that it's a non-chemical change because: 1. Non-chemical changes do not form a new substance. 2. They are generally reversible. 3. They are not accompanied by considerable heat change.
Yes, by utilizing a physical property like temperature or pressure, you can change the state of matter of a substance. For example, increasing the temperature of ice (solid) will change it into water (liquid), or increasing the pressure on water vapor (gas) can change it into liquid water.
Boiling water is a physical change, not a chemical change. The water molecules remain the same chemical composition (H2O) even though they change state from a liquid to a gas. This change is reversible.
Physical change. It is still water, it has simply changes from one form to another. Like ice freezes from liquid water... It's still water just a different state.
True. A change in state, such as from solid to liquid or gas, is a physical change because the substance's chemical composition remains the same and only its physical properties, like shape or state, change.
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.

I'd say no. Melting just changes the physical properties. Example: A rubber ball. If you melt a rubber ball it will still be rubber, just in a different form.

It causes matter to change by turning the water into gas which is vaporization, turning water into ice.
False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.
True. A change in oxidation number occurs when there is a transfer of electrons from one atom to another, leading to a change in the oxidation state of an element in a chemical compound.
Yes, freezing is change of state, from liquid to solid. Freezing is a physical change, not a chemical change.
