What type of change is an eyeshadow physical or chemical?
it is chemical because it can not be reversed
When a solid dissolves does that mean a chemical reaction happened?
Not necessarily be a chemical reaction. Dissolution of solids are generally physical properties, because if the solvent is removed, then we can get the solid back (in most of the cases).
Is Mass physical or chemical?
Mass is a physical property of matter that quantifies the amount of substance in an object. It is measured in units such as grams or kilograms and does not change regardless of the object's state or composition. Unlike chemical properties, which describe how a substance interacts during a chemical reaction, mass remains constant unless matter is added or removed.
Why is crayons changing the color on paper a physical change?
Crayons changing the color on paper is a physical change because it does not alter the chemical composition of either the crayon or the paper. The change is reversible, as the color can be erased or removed without chemically altering the substances involved.
Is jeans fading in the wash a chemical or physical change?
Jeans fading in the wash is primarily a physical change. This occurs as the dye molecules in the fabric are physically removed or broken down due to the action of water, detergent, and agitation during washing. While some chemical reactions may occur with certain detergents, the fading itself is mainly the result of the physical removal of dye.

Is perfume evaporating chemical or a physical change?
Physical as H2O and some other elements are only removed from the perfume istead of creating new substances Physical, because H2O and other chemical substances are removed instead of new chemical substance being created.

Why is the coke and Mentos experiemnt a physical reaction?
The Coke and Mentos experiment is a physical reaction and not a chemical one because the chemical compounds involved are not changed. No "chemistry" happens, but only "physics" occurs. Let's look. Carbon dioxide (CO2) gas is dissolved in the Coke, and when the cap is removed, it begins to come out of solution and form bubbles. There is a complex issue regarding exactly where a bubble will form and how it will grow, but bubbles do form and grow. Dump in some Mentos and the surface of each of the Mentos provides a "zillion" sites for bubbles to form. They form quickly, then detach, and more bubbles quickly form. This results in a cascade of bubble formation and the dramatic result we see. And it's all about the CO2 coming out of solution and making bubbles rapidly. Those bubbles carry Coke with them to the top of the bottle as they make their way out, and we see the fountain form. The Mentos and Coke are unchanged, just as the CO2 is unchanged in this physicalreaction.The reaction of Diet Coke and Mentos is a physical reaction. Links can be found below to learn more.

Why is a champagne glass called a flute?
Champagne glasses are taller and more narrow than normal wine glasses. Other than that there isn't a big difference between the two. One is just used for champagne and the other is used for wine.
Is washing cloths is a chemical change?
Washing clothes is a physical change, not a chemical change. The dirt and stains on the clothes are being physically removed, but the molecular structure of the clothes remains the same.
When a solid dissolves does that mean a chemical reaction happened?
Not necessarily be a chemical reaction. Dissolution of solids are generally physical properties, because if the solvent is removed, then we can get the solid back (in most of the cases).
