You may be wondering what is a chemical change or what is a physical change, or what is this campfire classified as?
a physical change is where a substance is changing states and it can be reversed back like water turning to ice back to water
a chemical change is when a substance is mixed with another substance and makes a new substance that cannot be reversed back to normal
