To find the density of a piece of coal, you would first measure the mass of the coal using a scale. Next, you would measure the volume of the coal using displacement method or a caliper. Finally, divide the mass of the coal by its volume to calculate the density, which is typically expressed in g/cm³ or kg/m³.
Use the blue inner flame when heating a piece of solid coal on a Bunsen burner. Adjust the air hole to control the intensity of the flame, ensuring efficient heating of the coal.
A burnt out piece of coal is one that has already undergone combustion and no longer contains enough energy or fuel to burn effectively. It appears as a charred, blackened fragment that is no longer useful for producing heat or fire.
A burnt out piece of coal is typically referred to as "coke." Coke is a porous, hard, and gray substance left behind after the volatile components of coal have been burned off. It is commonly used as a fuel and in industrial processes due to its high carbon content and low impurities.
