Coal ground into a fine powder is called what?

Explanation:
Pulverized coal is coal ground into a fine powder to maximize surface area and speed up combustion when it’s blown into a furnace with air. Grinding coal to tiny particles—often around 75 micrometers (about 200 mesh)—lets it burn rapidly and more uniformly, improving efficiency and control in pulverized-coal boilers. The other terms describe different forms of coal made for storage or transport: briquettes are pressed blocks, pellets are small rounded pieces, and slurries are coal suspended in liquid. So, the form described by the question is pulverized coal.
