True or False: When the particle size of coal is large, its surface viscosity decreases and its concentration increases, but the coal slurry tends to stratify, which is not conducive to storage. When the particle size of coal is small, its viscosity increases and its concentration decreases, which makes pumping difficult; therefore, an appropriate particle size distribution is necessary.
Error: when the particle size of coal is large, the surface viscosity decreases, and the concentration may increase
