is coal solid liquid or gas?

Coal, one of the most important primary fossil fuels, a solid carbon-rich material that is usually brown or black and most often occurs in stratified sedimentary deposits.

As Swamy Swarna correctly noted, iron is a metal while coal is a non-metal composed of carbon, volatiles (aromatic hydrocarbons), ash and some minor elements (such as sulfur). However, there is a connection between iron ore and coal, and it is this: ... This iron is called “pig iron”.

Proximate analysis of coal determines the moisture content of coal,volatile matter,ash content and fixed carbon of coal. Ultimate analysis determines the chemical composition of coal i.e Carbon,hydrogen,oxygen,nitrogen,sulphur along with moisture and ash.

Its primary constituents are macerals: vitrinite, and liptinite. The carbon content of bituminous coal is around 60–80%; the rest is composed of water, air, hydrogen, and sulfur, which have not been driven off from the macerals.

Coal is a Natural mineral whereas Charcoal is a man made mineral. Coal is a natural mineral that is formed under the earth's crust due to the prolonged decay of plant and animal matter due to the heat and pressure. ... As coal contains mainly carbon, the conversion of dead vegetation into coal is called carbonization.

Coal is formed from heat and pressure, just like diamonds. However, diamonds require much greater temperatures and far more direct pressure to form, which is a primary reason why the end result is so different. This extreme heat and pressure can only be found far into the earth.

Basically, these differences center around the fact that coal is found at its site of deposition as a solid and relatively pure massive organic substance, whereas petroleum is liquid and migrates readily from its place of origin into porous reservoir rocks. Kerogen is the main precursor material of petroleum compounds.

Key Points Matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. Liquid matter is made of more loosely packed particles.

Yes. Indeed, argon can be a solid, liquid or gas, depending on temperature or pressure. ... between -189.2 C (-308.6F)and -185.7 C (302.3F)it is a liquid, and above -185.7C (302.3F)it is a gas. Note that it has a VERY narrow temperature range for being a liquid.

Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests.

Solids, liquids and gases are known as states of matter.

Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.

Coal and petroleum are formed as a result of degradation of ancient plant life which lived millions of years ago. These dead plant matter started to pile up, eventually forming a substance called peat. Over time, heat and pressure from geological processes transformed these materials into coal.

Three states of matter exist – solid, liquid, and gas. Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.

A solid is matter that has a fixed volume and a fixed shape. A liquid is matter that has a fixed volume but not a fixed shape. A gas is matter that has neither a fixed volume nor a fixed shape. Like a gas, plasma lacks a fixed volume and shape.

solid: Has a definite shape and volume. liquid: Has a definite volume, but take the shape of the container. gas: Has no definite shape or volume.
