Physical Changes: 1. Broken Glass The glass was chipped and it's categorized as a physical change because something affected the actual object and it didn't have anything to do with a chemical change. 2. Ice Cube Melting The Ice Cube was condensating and because of the warmth, the ice was slowly changing back to its liquid state. Because it has nothing to do with chemicals, it only changes physically. 3. Ripping Paper While I was ripping the paper I knew that nothing was changing chemical wise it was just the fact of my physical doing is why it was changing and it's categorized as a physical change.
Chemical Changes: 1. Burning Candle I observed that when I add the fire to the candle, the candle starts burning and the wax starts to melt. And I already know that fire needs oxygen to burn. So that's how it's categorized as a chemical change. 2. Dissolving Salt In Water I observed that when salt is mixed into water and the state of the salt changes. The salt mixes in with the water and it dissolves and with chemicals working together, that's the only way that can happen. 3. Digesting Food Just like everyone I eat, and I realized that while eating the food is digested with chemicals inside of us humans and that breaks down the food and digests it. That's a chemical change because the food does change its form, it's a chemical change.
