Initially it'll be a chemical change...but a rusted oil drum is also a weakened one, and (especially if you piled other drums on top of it) it could change shape through applied external forces lower than ones normally needed to change the shape of an oil drum, and that would be a physical change.
Any sort of rusting is a chemical change.
KOH is the chemical formula for Potassium Hydroxide, so a drum of potassium hydroxide.
The area in which you drum will not change the pitch but change the way in which you hear the drum. The sound may last longer or less, it may be loud or quiet.
yes!
Tighten or loosen the drum-skin.

To safely open a plastic drum with a chemical inside, first know the type of chemical. Then, apply all safety equipment including clothing coverings, eye and face protection, and gloves. Then remove the lid.
The Snare drum.. The metal is the snare.
To chnage the volume of a drum, you must increase or decrease th energy you use to hit the drum. Hope this helped
on my civic there are two bolt holes in the face of the drum, they are metric thread , you will need to get two bolts and thread them in at equal rates and the drum should "POP" off. they will get tight before this happens . a little oil on the threads will help as they are usually a little rusted up , hope this helps
Cavalier's were made with both and the cars model wont even tell you which size your cavalier has. You need to take off the wheel and try to read the stamp on the drum or if it's too rusted you'll have to take off the drum and measure the inside diameter where the shoes sit.
No, the value will not change at all. If you replace drum brakes with drum brakes as you said youwe're doing, it is the same as it is now, so no value change there unless you change something and replace it with something different, then you may have some value change.
No, it is a physical problem, like getting cut.
