Is crushing a can a chemical or physical change? [Answered!]

The crushing of a can is a physical change because you are not changing the chemical compounds of the can because you still have a can. If the can was burnt, for example, then it would be a chemical change. It is a physical change because even though it is being crushed, it is still a can but it is just changed shape.

Is a crushed can a physical or chemical change? [Expert

The Chemistry of Garlic Allicin is made when two substances present in garlic, alliin and allinase, interact a chemical reaction that only occurs when the cells of the clove are broken down, through cutting, crushing, slicing or (for the brave!) biting.These are not definite indicators; a chemical reaction may not be occurring. A change in color is not always a chemical change. If one were to change the color of a substance in a non-chemical reaction scenario, such as painting a car, the change is physical and not chemical. This is because the composition of the car has not changed.Chemical Change vs. Physical Change Chemistry LibreTexts

Cement Clinker Manufacturing Process with Reactions

The reactions at this stage are: 12 CaCO3 + 7 Al2O3 → Ca12Al14O33 + 12 CO2. 4 CaCO3 + Al2O3 + Fe2O3 → Ca4Al2Fe2O10 + 4 CO2. 4 CaCO3 + Al2O3 + Mn2O3 → Ca4Al2Mn2O10 + 4 CO2. Decomposition of remaining calcite: A little amount of calcite remains at this stage and forms free lime for the first time: CaCO3 → CaO + CO2.3.1 Introduction to Crushing and Grinding of Bauxite. The most common initial process step to feed an alumina refinery with bauxite is the crushing or sizing of the raw bauxite material that is extracted from the mine. The feed material is crushed or sized so that it is conveyable, as well as correctly dimensioned, for the next step in the process.Physical Bauxite Processing: Crushing and Grinding of Bauxite
