Soft coal, also known as lignite, transforms into harder forms of coal such as bituminous coal or anthracite when subjected to increased heat and pressure over millions of years. This process is known as coalification.
Coal turns into a solid material called graphite when subjected to high heat and pressure over time. Graphite is a crystalline form of the element carbon, with distinct properties such as its lubricating ability and use in pencils.
Under intense heat and pressure, the soft coal turns into hard coal.
Heat and pressure during the process of coal formation determine the type of coal formed. The higher the heat and pressure, the more carbonaceous the coal becomes, resulting in higher carbon content and quality. Low heat and pressure conditions lead to the formation of low-grade coals like lignite, while high heat and pressure conditions promote the formation of high-grade coals like anthracite.
Coal was formed from the remains of ancient plants that were subjected to high pressure and heat over millions of years. The organic matter in the plants was transformed into coal through a process known as coalification. Fire is not involved in the formation of coal, but the pressure and heat from the Earth's crust played a significant role.
Peat formation: Plant material accumulates in waterlogged environments, where decomposition is slowed, forming peat. Lignite formation: Over time, peat is buried and compacted, increasing pressure and temperature, transforming it into lignite, a low-grade coal. Bituminous coal formation: Further burial and compaction of lignite results in higher pressure and temperature, forming bituminous coal, a higher-grade coal. Anthracite formation: With increased heat and pressure, bituminous coal can undergo further metamorphism, producing anthracite, the highest-grade coal.
They melt. Coal turns to diamond.

When she said that, its true because if you've ever seen the movie Superman 3 in the end Superman gets some coal and with his heat vision he puts heat into it and at the same time he crushes it with his hands and it turns into a diamond. This isnt impossible to happen because coal really does turn into diamonds and coal with heat and pressure, the only thing is is that it takes a LOT of years to happen.

heat and pressure
It turns to heat.
Water, heat and pressure
coal
coal
It could recrystallize and form marble, under specific conditions of heat and pressure.
coal is made from heat and pressure but i dont kno natural gas
