A phase change is a physical property where a substance transitions from one state of matter to another, such as from solid to liquid, liquid to gas, etc.
Yes, the condensation of ethanol is a physical change because it involves a change in the state of matter (from gas to liquid) without any change in the chemical composition of the substance.
A physical change is a type of matter change in which the substance's chemical composition remains the same, and no new substances are formed. Examples of physical changes include changes in state (solid to liquid), changes in shape, or changes in size.
Heating sulfur is a physical change. You're not changing the chemical composition of the sulfur, just the temperature. Now if you heat it to its boiling point and and it changes to a vapor it's a chemical change because you've changed its state of matter.(Actually changing the state of matter of an object is still a physical change, as it does not change the chemical composition of the element)
The evaporation of water is an example of a physical change, where water changes from its liquid state to a gaseous state without any change in its chemical composition.
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
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.
Change of state of a substance is a physical property!
Molecules can change states of matter through the processes of melting, freezing, vaporization, condensation, and sublimation. These changes in state occur when the temperature or pressure of the substance is altered, causing the molecules to rearrange in a way that transitions the substance from one state to another.
By heating or freezing.
Yes, by utilizing a physical property like temperature or pressure, you can change the state of matter of a substance. For example, increasing the temperature of ice (solid) will change it into water (liquid), or increasing the pressure on water vapor (gas) can change it into liquid water.
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.

For a substance to change from one state of matter to another, energy must be added or removed to break or form intermolecular forces. The temperature and pressure conditions must also be appropriate for the desired state change to occur, such as melting, boiling, or freezing.
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.
