When a physical change occurs, a substance’s physical properties may change, but its chemical properties will not. It will still have the same molecules arranged in the same way. For example, let’s say you saw a log in half. That will change the size of the log, but not its chemical makeup. What are other examples of physical changes? Crumbling aluminum foil will change the foil’s texture, popping a bubble will change the ice’s volume and heating an ice cube will change the bubble’s state of matter. All of those changes are physical. State of matter changes can be tricky, but remember those are physical changes, too. If a substance is just moving between solid, liquid and gas states, its chemical composition remains the same.

Which of the following would be the best title for this passage

Explanation:

When you inhale (breathe in), air enters your lungs and oxygen from the air moves from your lungs to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathe out). This process is called gas exchange and is essential to life
