Question

Q.2 differentiate between the following 1. cole and coke ​

Answer 1

Answer:

Charcoal is a fuel that comes from the incomplete burning of wood. ... Coke is a fuel that is obtained from the calcination or dry distillation of mineral coal. It is composed of carbon and has a high calorific value, but it is highly polluting.

Coal is a rock you dig out of the ground (that much I knew). Charcoal is a man-made product, and it's made from wood. You make charcoal by heating wood to high temperatures in the absence of oxygen. ... Confusingly, charred coal is called “coke”.

Coal:

1)It is a naturally occurring substance.

2)It has volatile matter.

3)It has high mechanical strength.

4)It appears to be a solid mass physically.

5)It has high specific gravity in the range of 0.77

Coke:

1)Artificially prepared from few impurities and high carbon content.

2)It contains relatively low volatile matter.

3)It has relatively low mechanical strength.

4)It has a porous physical appearance.

5)It has relatively low specific gravity.
