PHASE CHANGE Meaning and
Definition
-
Phase change refers to the process by which matter undergoes a transition from one physical state to another, such as from a solid to a liquid, a liquid to a gas, or vice versa. It occurs in response to changes in temperature or pressure. During a phase change, the arrangement and movement of particles within a substance are altered, resulting in a transformation of its physical properties.
One commonly observed example of a phase change is the transition from water to steam. As heat is applied, the temperature of the water rises until it reaches its boiling point. At this critical temperature, the phase change occurs, and the liquid water rapidly converts to its gaseous state, steam. Similarly, the reverse process can take place, as steam is cooled below its boiling point and condenses back into liquid water.
During a phase change, energy is either absorbed or released from the system. This energy is known as latent heat, and it is required to break or form intermolecular bonds between particles. For example, the latent heat of fusion is the energy absorbed or released during the phase change from solid to liquid or vice versa.
Understanding phase changes is crucial in various fields, including chemistry, physics, and materials science. It has implications in industries such as energy production, manufacturing, and environmental studies. Furthermore, phase change materials (PCMs) are substances specifically designed to exploit their ability to undergo phase transitions for practical applications, such as storing and releasing thermal energy.

Etymology of PHASE CHANGE
The word "phase" comes from the Greek word "phasis", which means "appearance" or "manifestation". In the context of science, a phase refers to a distinct state of matter, characterized by its physical properties and structure.
The word "change" comes from the Old English word "cyngan", which means "to become different or alter". It has its roots in the Proto-Germanic word "khwengan", meaning "to bend, yield".
When combined, "phase change" refers to the alteration or transformation of matter from one state or phase to another. It is commonly used to describe the transition between solid, liquid, and gas states, but can also be used in the context of other transformations, such as changes in magnetic, electric, or atomic properties.
