Answer:
Physical
Explanation:
The change of density alone is a physical change, but there might be some chemical change that results in physical change. For example: Burning a piece of paper will definitely change the density of the paper as some of its content is being changed into smoke which is a gas. So there will be a change in volume which in turn leads to change in density. Therefore, the change of density alone is a physical change, but the change might occur due to another chemical change.
