About 1 - 3 on the Mohr's Scale.
Coal can vary in hardness from soft lignite to very hartd anthracite.
However, in all cases it is much softer than diamond ( 10 on Mohr Scale).

What is the hardness of coal on the Mohs hardness scale?
Coal, as an organic sedimentary rock, is not determined to have a hardness on the Mohs scale of mineral hardness.
What is the hardness of bituminous coal?
Bituminous coal has a hardness ranging from 1.1 to 2.2 on the Mohs scale, which measures the hardness of minerals. It is considered to be relatively soft compared to other types of coal, such as anthracite coal.
What is the hardness of coal on the Mohn hardness scale?

What is the hardness of slag coal?
Slag is not a coal variety that has a typical hardness measurement. Slag is a byproduct formed during the smelting or refining of materials such as coal or metal ores. Its hardness can vary depending on its composition and production process.
The Mohs hardness of coal?
The Mohs hardness of coal is typically around 1 to 2. This means coal is a relatively soft mineral and can be easily scratched with a fingernail or a copper penny.

Is wood being softer than coal a physical property?
Yes, the hardness of a material is a physical property. Wood is softer than coal, meaning it has a lower hardness and can be easily scratched or dented compared to coal.
What is bituminous coals relative hardness?
Bituminous coal has a relative hardness of around 2-2.5 on the Mohs scale, which measures the hardness of minerals based on their ability to scratch another material. This places bituminous coal at a moderate hardness level compared to other minerals.
What is the hardness of anthracite coal?
Because it is a rock, not a mineral, the Mohs value will vary significantly from sample to sample. An average range would be between 3.0 and 3.8.
Is coal on the Mohs scale of hardness?
Yes, coal is not officially assigned a Mohs hardness value as it is not a mineral. However, coal is generally regarded as a relatively soft material compared to most minerals, and can be easily scratched with a fingernail or copper coin, which are examples of materials with hardness ratings lower than 2.5 on the Mohs scale.

Is coal hard?
Anthracite coal is harder than bituminous coal. Anthracite coal has a relative hardness of 1.3 to 1.4. Bituminous coal has a hardness of less than one.
