I think you mean "Is burning a paper a physical change?" Burning a paper is not a physical change. It is a chemical change. Because you can't turn the ashes of the paper into a normal paper again. Examples of physical change: Cutting a paper, sharpening a pencil, writing on a paper... Examples of chemical change: Rotten egg, Rusted steel, molded bread...

A physical change is any change that doesn't affect substance's chemical makeup or chemical properties.Physical changes include (but aren't limited to): a substance being crushed, cut, torn apart, or powdered.For example, cutting a big log into smaller pieces is a PHYSICAL change (because the wood has the same properties before and after being cut), whereas burning the wood would require changing the chemical makeup of the wood (thus being a CHEMICAL change).
Cutting a rope is a physical change. Burning a rope, or disolving it in acid, would be a chemical change.

No, it is a physical change. If you think about cutting the wood, the pieces will be smaller than the log, but they will have all of the same properties as they did when they were put together. An example of a chemical change is burning the wood. The act of burning it would be a chemical change since it is converting the wood into carbon and water vapor.
