Is color a physical change?
Only if the color change is not permanent. Take Iodine for example (that's pronounced Eye-oh-deen), it is a solid metal that is grayish in color in its solid state, however in its gas state it's a purple or violet color. Once it reverts to its solid state, it turns gray again. This is a PHYSICAL property of Iodine. If the color changed permanently to something else, it would be a chemical change.
Color change is a chemical change, not a physical change!
color is a physical and intensive property
- Color is a physical property and the change of color also. - Color change may be a sign of a chemical reaction.
Color is a physical change always.
Color is a physical property, not a change.
A physical change is when the object changes shape, color, or physical state.
Each color is a physical PROPERTY, not a change and surely not chemical. Color may change through a chemical or physical influence (chem reaction, heating, illumination etc.)
Color is not a physical change, it is a physical property. It is considered a physical property because, while it is an obvious property, it has nothing to do with how it reacts with other substances.
This is a physical change.
Color is a physical property.
Color change is associated to a chemical change
Physical. A physical change is a change in shape, size or color without a change in molecular structure.
Color is a physical property.
yes they do!
A physical change, of course. A physical change includes change in shape, color, or texture.
It is a physical change because it might change to a different color if rubbed
An object being purple is a characteristic, not a change.
A change in the color of solution is a sign that a physical change has just occurred.
no, a physical change
A color change is only a chemical change if the change is permanent, if the color change is not permanent, then it is likely a physical change. Let's look at Iodine for example (that's pronounced Eye-oh-deen), it is a solid metal that is grayish in color in its solid state, however in its gas state it's a purple or violet color. Once it reverts to its solid state, it turns gray again. This is a… Read More
A physical change is simply, a temporary change, which changes the physical characters of an object like its color, shape, size etc. It is a reversible change.
Change in Color.
Isn't that a physical change?
The color of copper wire would be a physical property.
Color is a physical property. However, change in color is a sign of a chemical reaction.
As far as chemicals go, no. In fact, color change is an indicator of chemical change.
Color isn't a "change" of any kind, it's a property. A change in colors is usually due to a chemical change, but there are a few special cases where it's a physical change (such as in a mood ring).
Any color, or even lack of color, is a physical property. Mixing 2 substances together and getting a cange in color may be evidence of a chemical change, but just looking a one substance and describing its color is a physical property.
If you burn a soap it will change in odor in (chemical change) And the physical if the color it will not be change!
Blue color is a physical change because it is observed with the senses and can be determined without destroying the object. :) good luck!
when the things have been change in color or size its already known that its a chemical but if it is the same size and color it still physical
The change is leaf color is a chemical change.
change in state,shape, or no color change
a chemical change
a physical change is not a chemical change as it changes the physical appearance of the substance like state, color, size and shape
It depends. In most cases, it is a chemical change as the different colored species have different chemical structures. However, it is possible to change color by very finely dividing particles of matter and this is a physical change.
Because a physical change just alters the appearance of an object, where as a chemical change alters the texture or state of an object.
Odor, precipitate forms, color change. these are not physical changes these are chemical changes
a chemical change
It is a chemical change.
This change is chemical.
chemical and physical
It is a physical change. Preexisting pigments are moved to and from the surface of the skin, but the pigments themselves do not change.
Color change indicates either a physical change or a chemical change. The physical change would be the two or more substances mixing together and changing the color due to the different colors of the substances. However, color change could also mean that the compounds or elements formed a totally new compound/elements, showing a chemical change.
Blue color is a physical property. It is a physical property because being blue does not change the chemical composition.
