Peat coal has ______ carbon and ________ moisture content ?

Low, high

The correct answer is option 2. Low, high.

Peat is the precursor to coal and is considered an early stage in the formation of coal. It is an organic material that forms in waterlogged conditions, primarily in peat bogs or marshes. Here's an explanation of why peat coal has low carbon and high moisture content:

1. Low Carbon Content: Peat is primarily composed of partially decayed plant material, such as mosses, grasses, and other organic matter. The incomplete decomposition of these plant materials means that the carbon content in peat is relatively low compared to more advanced forms of coal. The carbon content gradually increases as peat undergoes further geological processes and transforms into lignite, bituminous coal, and eventually anthracite.

2. High Moisture Content: Peat is characterized by its high moisture content. The waterlogged conditions in which peat forms contribute to the preservation of water within the organic material. The high moisture content is a distinguishing feature of peat, and it makes the material relatively soft and less dense compared to more mature coal types.

As peat undergoes geological processes like burial, compaction, and heating over time, it can transform into coal with higher carbon content and lower moisture content. The transformation from peat to coal is part of the coalification process, and the resulting coal types exhibit varying degrees of carbon content and energy density.
