All living organisms have the catalase in their body to neutralise the toxic hydrogen peroxide formed due to various metabolic activities to water and oxygen. So by grinding it may speed up this decomposition reaction.
it will be heavier and it will turn different colors. Also it will decrease the rate
yes, catalase is found in inorganic material. For example: Sand

You need a very hard substance for grinding tools such as aluminum nitrite, tungsten carbide or industrial diamond. The material is in small particle form, which is adhered to the grinding surface.
This question is incorrect. Dry grinding is used in ceramic industry. It's very usual in Brazil
sanding has a soft backing it tends not to cut work material grinding has a hard backing it cuts or machines material
When grinding, an abrasive material such as carborundum is used to remove material from the workpiece. When turning, material is removed from the workpiece with a cutting tool. The worpiece is usually clamped in the jaws of a chuck, and the chuck turns. the tool is clamped to a toolpost and moved along the workpiece and into the workpiece in order to cut material off in a measured amount.
In 1880, the cost of a grinding stone would have varied depending on the size, material, and quality. However, generally speaking, a basic grinding stone would have cost around a few dollars at that time.
The surface area increase by grinding and the possibility of contact of water molecules with the material of course is higher.
Subtractive - because they remove material from the object being ground.
lifting their loose particles by abrasion,grinding and by dissolving soluble material
For example, by increasing the temperature, by grinding the material, treating with chemicals.
