You're thinking of a chemical change, a process by which you get a form of matter that you didn't have before. It's not really accurate to think of it as changing one substance into another. That sounds too much like alchemy, which is a pseudo-science. Rather, you simply rearrange the matter you had before into a new form, kind of like disassembling a LEGO sculpture and reassembling a new one using the same old pieces.
A change of one substance in a material to a different substanceis called a chemical change. One example of a chemical change is the rusting of iron.
This is a chemical reaction, a chemical change.

Physical change
Wood is a material (substance) not a chemical compound (it is not a pure substance made of one compound) and surely it is not a change at all, neither chemical nor physical.
This would be a chemical change. The other type would be a physical change. In a physical change the identity of the material does not change.
False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.
A substance is any matter, any material which has mass and occupies space. As far as a specific substance, a material has a specific constitution.An element is a pure substance which cannot be broken down into (or synthesized by) other substances.For example, water is a substance, but water itself is the result of the union of two other elements, hydrogen and oxygen.An element cannot be made by joining other substances together (example, gold).
A phase change.
A physical state is physical and not chemical Physical Property is observed without changing a substance into another substance. Chemical property is the ability of a substance to change into different substance.
Wood is a material (substance) not a chemical compound (it is not a pure substance made of one compound) and surely it is not a change at all, neither chemical nor physical.
One substance changing into a completley different substance. It cannot be reversed.
A physical change is one you can see. It changes the size, shape, or color of something. A chemical change is one that changes the composition of something. Basically, when a substance is changed into a different substance.
PHYSICAL CHANGE - refers to the change in size, shape, or state of matter. CHEMICAL CHANGE - happens when one chemical substance is transformed into one or more different substance, such as iron becomes rust.
Its the change of one substance into another substance.
A change from one or more substances to another is a chemical change.
This would be a chemical change. The other type would be a physical change. In a physical change the identity of the material does not change.
A chemical change produces a new substance with different properties than the original substance.
A physical change is one in which the shape, size, appearance or state, of a substance may alter, but its chemical composition remains same.
chemical change is the change of one substance into another substance.
When fire is produce the substance is burned and the obtained substance is having property completely different from previous one.
