Understanding Physical Change
A physical change refers to a transformation that affects one or more physical properties of a substance without altering its chemical structure.
Characteristics of Physical Change:
- No New Substance Formed:
- During a physical change, the original substance remains the same. For example, when ice melts into water, it is still H2O.
- Reversible Nature:
- Many physical changes can be reversed. For instance, freezing water back into ice is a simple reversal of the melting process.
- Change in Physical Properties:
- Physical changes can involve changes in state (solid, liquid, gas), shape, size, or texture. For example, cutting a piece of paper changes its size but not its chemical composition.
Examples of Physical Change:
- Melting:
- Ice melting into water.
- Dissolving:
- Sugar dissolving in water; the sugar can be recovered by evaporating the water.
- Evaporation:
- Water turning into steam; again, it can return to liquid form.
Conclusion:
In summary, the correct answer is option 'C' because a physical change involves a modification in physical attributes without inducing a chemical transformation. Understanding physical changes is essential in distinguishing between different types of changes substances can undergo in science.
