The statement that correctly explains why the ashes of burnt paper have less mass than the original paper is: **"some of the atoms in the paper become gases."**
When paper burns, the chemical reaction mainly involves the paper reacting with oxygen in the air. This process produces gases (like carbon dioxide and water vapor) that are released into the atmosphere, leading to a loss of mass in the remaining ashes. The other statements do not accurately describe the process involved in burning paper.
