Question

Which of the following is a solid fuel?
A.Kerosene
B.LPG
C.Charcoal
D.Methane

Answer 1

Various forms of solid material that can be burnt to release energy, giving heat and light through the process of combustion is known as Solid Fuel. Solid fuels can be in contrast with liquid fuels and gaseous fuels.

Complete step by step answer:
Fossil fuels contain carbon and hydrogen bonds. There are three types of fossil fuels they are; solid fuel, oil and natural gas. Solid fuels include wood, Hexamine fuel tablets, charcoal, coal, peat, and pellets made from wood, wheat, rye corn, and other grains.
Kerosene is a liquid mixture of chemicals, produced in the distillation of crude oil. Crude oil is distilled in a distillation tower to produce kerosene, diesel and gasoline.
LPG or Liquefied petroleum gas, is a mixture of hydrocarbon gases used as fuel in cooking equipment, heating appliances, and vehicles.
Charcoal is porous black solid, consisting of an amorphous form of carbon, obtained as a residue when wood, or other organic matter is heated in the absence of air.
Methane, a natural gas, is the cleanest burning fossil fuel. When methane is produced from non-fossil sources such as food and green waste, it can literally take carbon out of the air because it is able to trap heat in the atmosphere.

Therefore. The correct answer is option (C).

Note: Solid fuels in contrast with liquid fuels or gaseous fuels cheaper, easier to extract, more stable to transport and are even more readily available. Coal, specifically, is utilized in the generation of 38.1% of the world’s electricity because it is less costly than its liquid and gas counterparts. Therefore, solid fuels are also heavier to transport, require more destructive methods to burn and often have higher carbon, nitrate and sulphate emissions. With the exception of sustainable wood and biomass, solid fuel is normally considered non-renewable as it requires thousands of years to form.
