Final answer:
Transformation can occur as physical changes, where the shape or state of a material is altered without changing its chemical composition, or as chemical changes, where the substance's composition itself is modified. Flattening, rolling, and turning into felt are examples of physical transformations, while irreversible alterations often indicate chemical changes.
Step-by-step explanation:
The different ways in which something can be transformed include physical and chemical changes. For example:
- Flattening objects changes their shape but not their substance, which is a physical change.
- Rolling an object such as clay may alter its form, again representing a physical change.
- Turning substances into felt involves interlocking fibers, which can be both a physical process (assembling the fibers) and a chemical process (if a binder is used).
- When an object cannot be fixed, it may have undergone an irreversible chemical change.
- Water turning into snow is a physical change as it's a change in state from gas to solid.
- Cutting hair is a physical change, as it alters appearance without changing chemical composition.
- Converting bread dough into fresh bread in an oven is a chemical change because the components react to form a new substance.
