The transformation from [1] to [2] from the given diagram should be labeled as physical change or
Concept Introduction:
In any chemical reaction, new substances are produced by combining two or more substances with each other or by breaking down one substance into many.
When change only occurs in the form or state of any substance, it is known as physical change and it does not cause a change in substance composition.

Interestingly, all of the carbon dioxide and much of the water exits the body through the lungs: on every breath, the average person exhales 500 ml. of air, which is typically enriched to 4% CO, and 5% water vapor by volume. In short, when a person loses weight by dieting, the weight that is lost actually departs his body as a gas, every time he exhales. Each kilogram of body fat lost requires exhaling about 2.8 kg of carbon dioxide. Calculate how many breaths it takes an average person to "exhale" 3.00 kg of fat. Round your answer to the nearest thousand. You'll need to know that the density of CO₂ is 2.0 kg/m³. 10 13 ?
