What else can I help you with?
Is coal a black diamond?
No, coal and diamonds are two distinct substances. Coal is a fossil fuel formed from prehistoric plants, while diamonds are crystalline forms of carbon. Both may be used for various purposes, but they have different compositions and properties.
The energy in petroleum and coal is stored as what energy?
The energy in petroleum and coal is stored as chemical energy. When these substances are burned, the chemical bonds are broken, releasing heat energy in the process.
Is diamond and coal minerals?
Yes. Both diamond and coal are formed from carbon.
Which substances provide energy?
Carbohydrates, fats, and proteins are macronutrients that provide energy to the body. When these substances are broken down through digestion, they release energy that is used by our cells for various functions.
Why is coal referred to as black diamond?
Probably because both coal and diamond are composed of carbon.
Will a diamond turn back into coal?
No,The process in which turns coal into diamond cannot be reversed or "undone"
Coal and diamond are two different forms of carbon which is more dense?
Diamond is more dense than coal. This is because diamond has a more tightly packed crystal structure, making it denser compared to coal which is less compact.
Which element is found in coal and diamond?
Both coal and diamond contain the element carbon. However, the arrangement of carbon atoms in coal and diamond differs, leading to their vastly different properties.
Is coal stronger than diamond?
No, coal is not stronger than diamond. Diamond is one of the hardest known natural materials, while coal is much softer and less durable.
What phases does coal go through before it forms a diamond?
Coal goes through several phases before it forms a diamond. First, it undergoes burial and becomes peat. Over millions of years of high pressure and heat, peat transforms into lignite, then into bituminous coal, and finally into anthracite coal. If the conditions are right, further heat and pressure can turn coal into graphite and eventually into diamond.
What do a diamond and a lump of coal and graphite have in common?
both a diamond and a lump of coal are primarily composed of the element Carbon (C)
Is Coal and mineral?
Yes. Both diamond and coal are formed from carbon.
