Frost Wedging- water expands when frozen. Unloading- rock expands and breaks. biological- animals and plants dig up rock.
Examples: iron sulfide and some copper alloys.
Examples of chemical changes in matter include burning wood (combustion), rusting of iron, cooking an egg, and fermenting grapes to make wine. These processes involve the rearrangement of atoms in the substances, resulting in the formation of new chemical compounds with different properties.
Some examples of chemical species are atoms, molecular fragments, molecules, and ions. These are subjected to a chemical process or to a measurement.
Some chemical changes when you are cooking are:burning the foodOVERcooking itUNDERcooking itsorry for only three examples. those are the ones that i can only think of so far.
Chemical weathering is caused by chemical reactions in the substance, for example, when oxidation causes rusting.
soem examples of chemical sedimantery rock are limestone, and gypsum.

Synthesis, decomposition, combustion, and oxidation are some examples of chemical changes (reactions) of matter.
Acid rain
Energy that is stored into something and released by a chemical reaction is known as chemical energy. Some examples of these are batteries, gasoline, coal, and food.
food or gas
flour or dough into chapati .
Wood, coal, gas.
Examples: chemical reactivity, flammability, tendency to explode, etc.
