What does it mean when there is physical change?
A physical change is one where no new substance is produced. Melting is an example of a physical change. When you melt iron, you get liquid iron, it's still the same chemical substance. If you melt copper, you get liquid copper, not liquid iron.
Does a physical change mean that something has matured or grown up?
A physical change doesn't involve the molecule composition of a substance.
What does a substance mean?
A pure substance is a substance that cannot be separated by means of physical separation but only by chemical. It is a change in time.
What does phisical change mean?
A physical change is a change in the form or appearance of a substance without changing its chemical composition. Examples include melting, freezing, bending, or cutting a material.

Is condensation of water vapour is chemical change or a physical change?
Condensation of water vapor is a physical change because it does not involve a chemical reaction. It is the process of gas turning into liquid without any change in the chemical composition of the substance.
What does it mean to say a physical change is reversible?
A physical change is reversible if the substance can return to its original state after the change has occurred. This means that the change does not alter the chemical composition of the substance, allowing it to be reversed through processes like melting, freezing, or evaporation.
Is making a mixture a physical or chemical changehi?
yes it is because it is not changing the substance. EDIT: yes it is what? Is it chemical or physical? You probably mean it is a physical change.
What type of chage is melting ice?
Melting ice involves a physical change, as it transitions from a solid state to a liquid state while maintaining the same chemical composition. The process does not alter the molecular structure of the ice, making it reversible.
What does the physical change mean?
A physical change means that only the appearance of the substance has changed. So if your tear up a piece of paper, its still paper so a physical change has taken place. If you heat or freeze water its only a change of state so its still a physical change. So long as the molecular or chemical structure of the atom/substance does not change it will always be a chemical change. H20 will always be H20.
What does the word physical change mean?

a change in the chemical properties of substance results in a?
A substance can take on three physical states: Solid, liquid, or gas. The main physical changes from a thermodynamic standpoint are the amount of entropy(disorder) of the molecules of the substance. Density, temperature, volume are also characteristically different at each physical state and can be used to manipulate compounds between the three.
