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.

Yes, changes in phase or state are considered physical changes because they do not alter the chemical makeup of the substance. Examples include melting, freezing, boiling, and condensing.

∙ 13y agoBecause the only part of matter changed in a object is the formation of atoms inside not breaking any bonds in any molecule or atom but only the formation

∙ 11y agono, they are physical changes related solely to temperature and pressure.

Are phase changes physical or chemical in nature?
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.
What is the transformation of a physical state of a substance into a different physical state?
The transformation of a physical state of a substance into a different physical state is called a phase change. This can include processes such as melting, freezing, evaporation, condensation, sublimation, and deposition. During a phase change, the substance's molecular arrangement and energy level are altered.
When matter changes from one state to another What is the process called?
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.
Changes that do not alter the nature of a substance?
Physical changes do not alter the chemical composition of a substance, only its physical appearance or state. Examples include changes in shape, size, phase (solid, liquid, gas), or state of matter (melting, freezing, dissolving).
Are state changes physical or chemical changes?
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
What is it called when the three states change?
changes of state are called phase changes.
What is the transformation of a physical state of a substance into a different physical state?
The transformation of a physical state of a substance into a different physical state is called a phase change. This can include processes such as melting, freezing, evaporation, condensation, sublimation, and deposition. During a phase change, the substance's molecular arrangement and energy level are altered.
Melting is an example of a?
Melting is an example of a phase change. The substance is going from the solid state to the liquid state.
What is the process called when a substance changes its physical state but not its chemical state?
This process is most generally called "phase transition". Specific example include dissolution, melting, freezing, condensation, and allotrope transitions.
When a solid changes state to a liquid what is it called?
sublimation and phase change
When matter changes from one state to onother what is it called?
A phase transition.
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
When matter changes from one state to another is called what?
Physical changes.
When platinum is heated then cooled to its original state is a physical change?
Yes, heating platinum and cooling it back to its original state is a physical change. This process involves a change in the state of matter (from solid to liquid and back to solid) without altering the chemical composition of the platinum.
Is a change in phase a chemical or physical change?
A change in phase is a physical change. It does not involve the creation of new substances with different chemical properties. The molecules in a substance rearrange themselves during a change in phase, but the chemical composition remains the same.
Into what will a gas turn when it condenses?
It becomes a liquid; this physical change is called liquefaction.
Are state changes chemical or physical changes?
