What is the differnece between precepitation formed in physical change and chemical chnge?
In a physical change, precipitation is formed when solubility limits are exceeded and a solid substance forms out of a solution, not involving a change in the chemical makeup of the substances involved. In a chemical change, precipitation occurs when two or more substances react chemically to form a new substance that is insoluble and separates from the solution.
Is state is physical or chemical?
A physical state is physical and not chemical Physical Property is observed without changing a substance into another substance. Chemical property is the ability of a substance to change into different substance.
What is the meaning of Physical Change What is the meaning of Chemical Change?
PHYSICAL CHANGE - refers to the change in size, shape, or state of matter. CHEMICAL CHANGE - happens when one chemical substance is transformed into one or more different substance, such as iron becomes rust.
Is boiling water on a stove chemical or physical change?
This involves a change of state of the water. Before, during, and after the boiling, it remains water. So, since the substance doesn't change its character, the boiling of water is a physical change.

Is it true that if a physical change that occurs when a substance changes composition by forming one or more new substances?
No, that statement is incorrect. A physical change does not involve changing the composition of a substance or forming new substances. It only alters the physical state or appearance of a substance without changing its chemical composition. When a substance changes composition and forms new substances, it is considered a chemical change.

Is a chemical change a physical blend of two or more components?
No. A chemical change is when the chemical identity of substance or set of substances changes to a new substance or set of substances. Physically blending or mixing two components is a physical change.
Is shoveling snow a physical change?
Yes. The act of moving a substance from one location to another is a physical one. The act of changing the state of the substance from one state to another can be physical also. But the act of altering the substance by adding or subtracting one or more of its components is a chemical change.
What is a change to a material that does not change its composition?
The kind of change described is referred to as a physical change. Examples of physical changes include, but are not limited to, changing the temperature or state of a substance, changing the shape of a substance, and breaking a substance into smaller pieces. A change that alters a material's composition would be classified as a chemical change.
How is a chemical change different from a physical change?
a physical change can be reversed a chemical one can'tA chemical change is when a new substance, with new and different properties, is produced. The identity of the original substance is changed. In contrast, a physical change is when one or more of a substance's physical properties have simply been altered; no new substance is produced.
Is the fermenting of cheese a physical change?
"A physical change is any change not involving a change in the substance's chemical identity. Matter undergoes chemical change when the composition of the substances changes: one or more substances combine or break up (as in a relationship) to form new substances" From This I gather that its a physical change as the cheese isn't changed into another substance, The cheese doesnt change, for example it doesnt taste or smell different, But its physical propertys do change it looks different
What property is one that involves the production of a new substance?
A chemical property involves the production of a new substance. This occurs when a substance undergoes a chemical reaction that results in the formation of one or more different substances with different chemical compositions.
