Both girls are partially correct.
Isabela is right in that the act of chewing food is a physical change. Chewing breaks food down into smaller pieces, which changes its physical form but doesn't alter its chemical composition at that point.
Mirabel is also correct in that digestion involves chemical changes. During digestion, the body chemically breaks down the food into nutrients and energy through various biochemical reactions.
So, the best answer is that both girls are correct, but they are describing different aspects of the process of eating.
