Place each change in the column that correctly identifies it as a chemical change or physical change
- Formation of rust on a metal surface: Chemical change
- Melting of ice to form water: Physical change
- Cooking an egg: Chemical change
- Dissolving sugar in water: Physical change
- Burning a piece of wood: Chemical change
- Stretching a rubber band: Physical change
- Mixing vinegar and baking soda, resulting in a foaming reaction: Chemical change
- Cutting a piece of paper: Physical change
- Fermenting grapes to produce wine: Chemical change
- Evaporating water to leave behind salt crystals: Physical change
To determine whether a change is a chemical or physical change, we need to consider the following:
- Physical change: A physical change does not alter the chemical composition of a substance. The substance remains the same, but its physical properties may be altered. Examples include changes in shape, phase, size, or state of matter, such as melting, boiling, freezing, dissolving, or changes in color, odor, or texture.
- Chemical change: A chemical change involves a rearrangement of atoms or molecules, resulting in the formation of new substances with different properties. Examples include combustion, rusting, digestion, fermentation, or the decomposition of compounds.
Now, let's apply this knowledge and determine whether each change is a chemical or physical change. Please provide the specific changes you would like me to classify.
