That depends on your definition of producing something new. If you cut lumber to build a table ... you have produced something new, but that is a physical change. Wood is still wood.
But if you mean combining two or more substances, like hydrogen gas and oxygen gas, and, after burning, you form water, then that is a chemical change.
This is a chemical change.
If you burn something it is a chemical change, however if you melt of boil it, it is a physical change.
lighting is a chemical change
Chemical change
Distilling is a physical change.
That would be a chemical change.

A physical change is one where just the appearance of something changes and a chemical change is where the genetic makeup of something changes.
When something fizzes and foams, it's producing some sort of gas within it, thus it's going from a solid/liquid to a gas (a physical change). But, this gas is likely not the same material that it came from. it's just a byproduct of a chemical reaction with in it (a chemical change).

Something that burns or is flammable would be a chemical change.
a physical change is a phase change, such as water to ice or water vapor. a chemical change takes place on a molecular level, producing a new substance.
In a chemical reaction something new is created. A chemical change is inreversible where as a physical change is. In a physical change nothing new is formed.
