Answer:
Physical change
Explanation:
Physical change is when the substance's physical appearance or property changes, but it's chemical composition remains the same.
Answer: Option (c) is the correct answer.
Explanation:
A change that does not bring any difference in chemical composition of a substance are known as physical change.
For example, shape, size, mass, volume, density, etc of a substance are all physical properties.
When ice melts then its state changes from solid to liquid. And, this change can be reversed by freezing the liquid water.
Hence, no change in chemical composition is occurring so, it is a physical change.
Whereas a change that brings difference in chemical composition of a substance is known as chemical change.
For example, precipitation, reactivity, toxicity etc are chemical property.
Thus, we can conclude that changing from one state of matter to another is a physical change.
