What consistency does pulverized coal have?

1. Granular

2. Powdered sugar

3. Talcum powder

4. Sand-like

The correct answer is: Talcum powder

Pulverized coal is a finely ground form of coal that resembles talcum powder in its consistency. This similarity arises because pulverized coal particles are extremely small, allowing for a very fine and uniform texture, much like the smooth texture of talcum powder. This consistency is crucial for its use in combustion processes, particularly in power plants, where the fine particles promote efficient burning and improved heat transfer. The other options describe different textures; for instance, granular refers to larger, more coarse particles, whereas powdered sugar, while also fine, does not capture the specific texture and properties associated with pulverized coal. Sand-like suggests a coarser, grittier consistency that does not accurately represent the extremely fine particulate nature of pulverized coal.
