You could dehydrate the coffee, turning it back into powder.
what causes the powder to move away from the center and to move sideways.
yes, baby powder is considered as matter because baby powder is a homogenous mixture.
Talcum powder is not overtly harmful to dogs, but remember that our four-legged friends need a bit of oil in their coats to keep them healthy. The oils are developed naturally, and are somewhat dependent of the animal's diet. Talc, talcum powder, might dry a dog's coat out a bit by absorbing these oils, so consider the reason for applying it and weigh the consequences. A call to a local vet wouldn't cost anything but a bit of time, and good information can almost certainly be had there.
Stomach powder for dairy cattle is made by crushing up antacid pill. The powder can then be administered directly to the cow or via a liquid given by mouth.
Well, you can't but they sell some hamster powder on PETSMART. So you should go there and buy some if you need. Trust me i wouldn't put baby powder on my hamster.
Irreversible... You could distill a cup of prepared coffee - until all the water boils off, but you would never get back the original coffee powder, or granules.
No, dissolving powder into water is a physical change, not a chemical change. The powder molecules are still the same chemical compounds as they were before dissolving, just dispersed in the water molecules.
It is a physical change because the boiling water will turn into steam (process called gas), and in reverse it will turn into water again (process called condensation). It will be the same substance all the time
The instant coffee and the water have not changed chemically or physically. It becomes a mixture, not a solution; the water is separate from the coffee powder. Therefore it is not a physical change.
Baking powder (baking soda + some acid salts) will release CO2 (carbon dioxide gas) when placed in water. So, even though, in theory, all reactions are reversible, it is not likely that baking powder in water is reversible once the CO2 gas has formed.
reversible?

No, coffee powder and instant coffee are not the same. Coffee powder is ground coffee beans, while instant coffee is a processed form of coffee that dissolves quickly in water.
The answer is because you ar
No, coffee powder and coffee grounds are not the same. Coffee powder is finely ground coffee beans used for making espresso, while coffee grounds are coarser and are the leftover residue after brewing coffee.
No because if you put water in a pan and then ad coffee powder and evaporate it the coffee powder won't evaporate with it. If the powder does not settle to the bottom if left undisturbed for a while, then it is in solution (dissolved). Solutions can be of either a physical or chemical nature. Salt water is a solution as well, despite that salt will be left behind if the water evaporates.
when green powder is heated, it turns black and a gas is produced. in irreversible changes, new materials are always formed. given that a gas is produced, which is a new material, heating green powder is an irreversible change.
