a chemical change
in fact all are chemical changes.
all the options given are chemical changes.
Melting is an example of a physical change because it does not change the chemical composition of the substance undergoing the change. Tarnishing, rusting, and burning are examples of chemical change because they are caused by chemical reactions, which change the chemical composition of the substances undergoing the change.
melting any metal is physical. rusting iron is chemical
Well, darling, a physical change involves a change in appearance, like cutting a piece of paper, while a chemical change involves a change in composition, like burning that paper to ash. So, in simpler terms, physical changes are like a makeover, just changing the looks, while chemical changes are like a complete transformation, changing what's on the inside. Just remember, physical changes are skin-deep, but chemical changes go straight to the core.
Rusting is a chemical property because it is irreversible. It changes the identity of the substance.
rusting, burning, polymerizing,
chemical change
Boiling does not involve a chemical change in property. Boiling is a physical change in which a substance changes from a liquid to a gas without changing its chemical composition. The other options (rusting, burning, fermenting) involve chemical reactions that result in changes to the chemical composition of the substances involved.
The process described involves a chemical change. Boiling is a physical change as it involves a substance changing state from liquid to gas. Rusting, fermenting, and burning are chemical changes as they involve rearrangement of atoms in the substances leading to new chemical properties.
something rusting, something burning. chemical changes can fool you because most of the time they change color and such. but if two substances mix to make a new substance than that is a chemical change.
Rusting is a slow chemical reaction between iron and oxygen, forming iron oxide (rust), while burning is a rapid chemical reaction between a substance and oxygen, releasing heat and usually producing light and smoke. Rusting occurs at a much slower pace compared to burning.
in fact all are chemical changes.
When rusting occurs the mass of the substance increases since the rusting material reacts with the oxygen in air
all the options given are chemical changes.
Physical - Breaking of glass Boiling of water Melting of ice Cutting of vegetables Chemical - Burning of paper Cooking of food Rusting of iron Souring milk
Both rusting and burning are forms of oxidation reactions. In both processes, a material combines with oxygen to form new compounds. Rusting typically involves the corrosion of metals, while burning is the combustion of organic materials, resulting in the release of heat and light.
