Question

What is the type of change that occurs in interconversion of states of matter?

Answer 1

Hint: A state of matter is one of the many different forms that matter can take. In daily life, four states of matter are visible: solid, liquid, gas, and plasma. Many intermediate states, such as liquid crystals, also exist, and certain states, such as Bose–Einstein condensates, only exist under extreme conditions.

Complete answer:
Interconversion of states is a physical transition since it occurs without a change in the substance's structure or chemical nature.
The term "state shift" refers to the transition of a substance's physical properties from one state to another.
Fusion or melting: Melting, also known as fusion, is a physical process that causes a material to transition from a solid to a liquid state. As the internal energy of a solid increases as a result of the application of heat or pressure, the temperature of the material rises to the melting point.
Vaporisation or Boiling: Vaporisation or boiling is the mechanism by which a material transitions from a liquid state to a vapour or gaseous state at a constant temperature by absorbing heat. The boiling point or evaporation point of a liquid is determined by a fixed temperature.
Condensation: Condensation is the transformation of water from a gaseous state (water vapour) to a liquid state (water). Hot air rises, cools, and loses the ability to retain water vapour, resulting in condensation in the atmosphere. Excess water vapour condenses to form cloud droplets as a result.
Freezing: Freezing is the process of a substance's liquid state changing to a solid state at a constant temperature by releasing heat, and the fixed temperature is defined as the freezing point.
Sublimation: Sublimation is the process of a material transitioning directly from a solid to a gas state without going through a liquid state. Example – Camphor.
Evaporation: The transformation of water from a liquid to a gas or vapour is known as evaporation. Evaporation is the most common way for liquid water to return to the water cycle as atmospheric water vapour.
Solidification: Solidification, also known as freezing, is a phase change of matter that produces a solid. When a liquid's temperature falls below its freezing point, this happens.

Note:
A given set of matter's state or phase will change based on pressure and temperature conditions, switching to other phases as these conditions change to favour their survival; for example, a solid converts to a liquid as temperature rises.
