Worse, black powder can be permanently ruined by water. This is because it's a mixture of saltpeter (potassium nitrate, K N O X 3 ), sulfur, and charcoal, and saltpeter is watersoluble. If you get it wet enough, the saltpeter can be completely washed out of the mixture.

Coal dust is a finepowdered form of coal which is created by the crushing, grinding, or pulverization of coal rock. Because of the brittle nature of coal, coal dust can be created by mining, transporting, or mechanically handling it.. Grinding or pulverizing coal to a dust form before combusting it improves the speed and efficiency of burning, which makes the coal easier to handle.

3. Cocoa is not soluble in milk. However, you can control the sedimentation by increasing the thickness of the milk, or decreasing the size of the cocoa particles. Nondairy milks can help with this as well. By the way, it is only the sugar that is dissolving, when you mix it with cocoa, and add that mixture to milk.

Introduction. In our previous studies, the combustion characteristics of highmoisture coal at high pressures were enhanced using liquid carbon dioxide (LCO 2) drying [1], with 37% combustion rate increase at 500 °C by means of LCO 2 drying for coal with 20% water content. The LCO 2 drying only takes 20 min to remove the same amount of water as oven drying for 8 h.
