∙ 9y agoSimplistically speaking, the statement is true - not wrong/false.
For example, one physical change is to fold paper. After the paper is folded, you can rather effectively unfold it and return it to its original condition. One chemical change is to burn something. After paper is burned, the ashes cannot be "unbunrt" back into paper.
However, some chemical changes are reversible. For example, photosynthesis is a chemical change in which water, carbon dioxide, and energy are turned into oxygen and sugars. Respiration is a chemical process in which oxygen and sugars are converted back into water, carbon dioxide, and energy. However, the process of respiration is much more complex than photosynthesis and is not the "reverse" of it, i.e. respiration is non un-photosynthesis.

irreversible
Is the lighting of a bulb a reversible or an irreversible change
Nearly, a physical change creates a substance and this is reversible. For example, ice-water. Water-steam. These are all reversible. A chemical change is irreversible. For example, baking a cake; you cannot get the original ingredients back again.

a physical change is reversible but a chemical change is irreversible
a physical change is reversible but a chemical change is irreversible
Chemical science, because yeast is irreversible. Chemical Change: Irreversible Physical Change: Reversible
Yes, because it can be reversed by condensation. Physical change = Reversible Chemical change = Irreversible
irreversible
irreversible change is called a physical change.
chemical change is reversible whereas physical is irreversible e.g a paper after getting burnt cant be converted to paper again this is a physical change
THE PHYSICAL CHANGE AND THE CHEMICAL CHANGE -physical change is characterized by the change of the physical state of an object and it is reversible while chemical change is irreversible since atoms and bonds are broken down to form a new substance

It is an irreversible change because it can not be reversed.
reversible. because you can melt it back to a liquid.
