Chapter 11, Problem 67TE

When you arise each morning, you measure your height again and consistently find that you are $1$ inch taller than you were the night before but only as tall as you were $24\text{hours}$ ago! Is what happens to your body in this instance best described as a physical change or a chemical change? Be sure to try this activity if you haven’t already.
