  2. Anthracite - Wikipedia

    en.wikipedia.org/wiki/Anthracite

    High grade and ultra high grade anthracite are harder than standard grade anthracite, and have a higher relative density. An example of a chemical formula for high-grade anthracite would be C 240 H 90 O 4 NS, [25] representing 94% carbon. [26] UHG anthracite typically has a minimum carbon content of 95%.

    — "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T. Kirke. The Precious Metals, Comprising Gold, Silver and Platinum .

  4. Coal analysis - Wikipedia

    en.wikipedia.org/wiki/Coal_analysis

    This removes high-ash value particle and increases the saleability of the coal as well as its energy content per unit volume. Thus, coals must be subjected to a float-sink test in the laboratory, which will determine the optimum particle size for washing, the density of the wash liquid required to remove the maximum ash value with the minimum work.

  5. Bituminous coal - Wikipedia

    en.wikipedia.org/wiki/Bituminous_coal

    Its bank density (the density of a coal seam prior to breaking up during mining) is about 1346 kg/m 3 (84 lb/ft 3) while the bulk density of extracted coal is up to 833 kg/m 3 (52 lb/ft 3). [12] Bituminous coal characteristically burns with a smoky flame and softens and swells during combustion. [13]

  6. Density - Wikipedia

    en.wikipedia.org/wiki/Density

    As there are many units of mass and volume covering many different magnitudes there are a large number of units for mass density in use. The SI unit of kilogram per cubic metre (kg/m 3) and the cgs unit of gram per cubic centimetre (g/cm 3) are probably the most commonly used units for density. One g/cm 3 is equal to 1000 kg/m 3. One cubic ...

  7. Kilogram per cubic metre - Wikipedia

    en.wikipedia.org/wiki/Kilogram_per_cubic_metre

    The kilogram per cubic metre (symbol: kg·m −3, or kg/m 3) is the unit of density in the International System of Units (SI). It is defined by dividing the SI unit of mass, the kilogram, by the SI unit of volume, the cubic metre. [1]

  8. Dietitians Say These Are the Best Diets for Weight Loss in 2025

    Category 1 (very low-calorie density): Unlimited portions. Examples: Non-starchy vegetables, fruits, broth-based soups, and nonfat dairy. Category 2 (low-calorie density): Moderate portions.

  9. Specific volume - Wikipedia

    en.wikipedia.org/wiki/Specific_volume

    If the size of the chamber remains constant and some atoms are removed, the density decreases and the specific volume increases. Specific volume is a property of materials, defined as the number of cubic meters occupied by one kilogram of a particular substance. The standard unit is the meter cubed per kilogram (m 3 /kg or m 3 ·kg −1).
