Is blue color a chemical property or physical property?
Blue color is a physical property. It is a physical property because being blue does not change the chemical composition.
Color change physical or chemical change?
Almost certainly chemical. Color ... that is, absorption or emission of electromagnetic radiation in the visible band ... is usually due to the electronic structure of the compounds. Changing the electronic structure usually means that a bond has broken or formed, which is a chemical change. However, certain types of color changes are physical. For example, when you heat a piece of metal and it begins to glow red, then orange, then yellow as you increase the heat, that's a purely physical change. Certain types of colors... like the swirling colors you see in a soap bubble... are produced by physical phenomena, and the changes there are physical (the color depends on the thickness of the soap film). "Mood Rings" are another example of something that exhibits a physical color change.
Is chromatography physical change?
Chromatography is a physical change because even though you are separating colors the original atomic identity of the colored ink being separated is still retained showing that a chemical reaction has not taken place.
Is cutting of tree a chemical change?
No. Trees' leaves change colors beacuase when winter comes around, they will not have the energy to keep leaves, so they seal off the leaves from the rest of the tree. When the leaves are cut off from the rest of the tree, the chlorophyll in them dies, and turns brown.
Is it true when a physical change that takes new substances are formed?
It is false. When a physical change takes place, the colors, texture, brittleness will change.
Is frying a fish a physical change?
Pan frying, no. It is a chemical change. Which is why it smokes and changes colors.
Why do colors bleed in the wash?
Both, physical change when chewing then chemical change when enzymes break it down
Is blue color a chemical property or physical property?
Blue color is a physical property. It is a physical property because being blue does not change the chemical composition.
Is color change a physical or chemical change?
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.
How do you classify a rose?
How would you classify the color of a rose? A. chemical changeB. physical changeC. chemical propertyD. physical propertyChemical change, of course. When the colors interaction with air occurs it affect the amount of oxygen flowing to the stem and alters the color greatly.So.... a. chemical change
Is a banana changing colors a chemical or physical change?
It's a chemical change. The sunlight stimulates the developing fruit to produce chemicals to help it ripen - in order to spread its seeds.
Is a rusty nail physical change or chemical change?
it is a Chemical change because before they are rusty they are perfect and they are a solid brown but over time they change colors because they are getting old H2O + air + metal = rust

When fall arives and the leaves on the trees change colors is it chemical?
These are chemical changes.
Is bread becoming mouldy physical or chemical change?
Bread has the right environment for mould spores to grow. It is warm (if kept out of the fridge), has a moisture content & the surface is textured perfectly for mould spores to take. Therefore it is a perfect host for their growth. As the mould spores grow, they consume the moisture in the bread and they spread into larger moulds as they consume more water. So in response to it being a chemical or physical change, there is something of both processes occurring. As the mould grows there are enzymes being produced by the mould which affect the bread and change its chemical nature, also the physical change is obvious as the bread shrivels due to dehydration. Also the colour and texture constitute a physical change. Hope this helps
