PHYSICAL CHANGE Meaning and
Definition
-
Physical change refers to a transformation that alters the appearance or state of a substance without changing the chemical composition of the material. It involves modifications in the physical properties such as shape, size, texture, or phase of matter, rather than the chemical structure or arrangement of atoms or molecules. In a physical change, the starting and ending substances remain the same, and only the external characteristics are modified.
These modifications may occur as a result of various processes, including heating, cooling, compression, dissolution, or evaporation. For instance, when a block of ice melts, it transforms into liquid water without any change in its chemical composition. Similarly, when water boils and turns into steam, it experiences a physical change.
Physical changes can typically be reversed or undone by altering the conditions or factors that caused them. For example, if the melted ice is cooled again, it can revert back to its solid state as ice. In contrast, chemical changes involve the formation of new substances with different chemical compositions, and they are typically irreversible. Physical changes can be observed and measured using various methods and instruments without requiring complex chemical analysis.
Understanding physical changes is essential in fields such as chemistry and physics, as they help explain how different substances react and transform under specific conditions.

Etymology of PHYSICAL CHANGE
The term "physical" comes from the Latin word "physicus", which originated from the Greek word "physis", meaning nature or natural. "Physical" refers to the natural world and the properties and processes found within it.
The word "change", on the other hand, comes from the Old English word "cang", which means to exchange or alter. It has roots in the Proto-Germanic word "kangjan", meaning "to become different" or "to change".
Therefore, the etymology of "physical change" suggests that it refers to alterations or transformations within the natural world or the properties and characteristics of matter and energy.
