the concept of phase state can also be applied to social change.
it can be impossible to predict the point/moment at which serious social change - good or bad - takes place. just as if one had never seen water boil before it would be difficult to predict what change would occur as the temp approached 212 F, it may be impossible/difficult to know at what point serious social changes might occur in a complex system.
an analogy: a mechanical levered light switch may move through a near-180 degree arc, but at some point the contact is made and the light goes on/off. if one had never seen this occur and did not know the underlying mechanism (which is certainly true for most factors in complex social situations!) it would be hard to predict what would happen at some point in the lever's movement.
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
The transformation of a physical state of a substance into a different physical state is called a phase change. An example of this is water changing from solid (ice), to a liquid (water), to a gas (steam).
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
The process is called a phase change or a change of state. This occurs when matter transitions from one physical state, such as solid, liquid, or gas, to another state due to changes in temperature or pressure.
Melting wax is a physical property because it does not change the chemical composition of the wax when it transitions from solid to liquid state. The process just involves a physical change in the state of matter.

changes of state are called phase changes.
Phase changes are physical changes, not chemical changes. They involve a change in the state of matter (solid, liquid, gas) without altering the chemical composition of the substance.
The transformation of a physical state of a substance into a different physical state is called a phase change. An example of this is water changing from solid (ice), to a liquid (water), to a gas (steam).
This process is most generally called "phase transition". Specific example include dissolution, melting, freezing, condensation, and allotrope transitions.
Melting is an example of a phase change. The substance is going from the solid state to the liquid state.
sublimation and phase change
A phase transition.
The temperature remain constant during a change of phase.
Physical changes.
Sublimation is the process when a solid changes directly into a gas without first becoming a liquid. This occurs when the conditions are such that the solid phase can bypass the liquid phase and enter the gas phase.
This process is called a phase change or a change of state. It involves the transformation of matter from one physical state (solid, liquid, gas) to another through the absorption or release of energy.
