What are the differences between graphite and coal in terms of their properties and uses?
Graphite and coal are both forms of carbon, but they have different properties and uses. Graphite is a soft, black, slippery material that is a good conductor of electricity and heat. It is used in pencils, lubricants, and as a material for electrodes in batteries. Coal, on the other hand, is a hard, black rock that is a fossil fuel used for energy production. It is burned to generate electricity and heat, and is also used in the production of steel and cement.
How energy is released from coal?
By Combustion (burning) Coal is a black shiny carboniferous rock. If heated to 'red' heat' it will combust, releasing carbon dioxide, and other gases in the process. The product of burning is commonly called ash, but when combusted under controlled conditions it makes 'coke' ( impure carbon).,
Name a type of rock that is burned as a fuel?

What sedimentary rock can be burned?
Coal is a sedimentary rock that can be burned to produce heat and energy. It forms from the remains of plant material that have been compacted over millions of years in swampy environments.
Which color rock would get the hotest a white or black?
Black absorbs heat, while white reflects heat away.
A black rock that can be use to make heat?
Black rocks such as basalt or obsidian can be used as heat-retaining cooking stones for grilling or baking. They absorb and store heat efficiently, making them useful for outdoor cooking or in traditional cooking methods. Simply heat them up in a fire or oven before using.
