How did fossil fuels form, and how are they obtained and used?

Usimov [2.4K]

Explanation:

Fossil fuels are important energy sources for our every day activities.

Formation of fossil fuels

Fossil fuels forms from the accumulation and burial of organisms in a basin of deposition. Instead of the organisms decaying, they preserve their carbon content. To be worthy of becoming fossil fuels, organisms must be buried in an environment where there is little to no oxygen to fast-track decomposition of the buried organic matter. Increase in temperature and pressure causes the organic matter to transform into fossil fuels.

How are they obtained

First, different fossil fuels have their extraction techniques because they occur in different physical state of matter.

For the solids e.g coal: exploration is carried out first and if a prospect is delineated, mining engineers design the best way to extract the coal from nature. Coal is usually found laid in sedimentary beds in nature. Top layers of sediments can be removed to extract the coal.

For fluids such as crude oil and natural gas, after a prospect is identified, a rig is usually constructed to extract the fluid and gas. The natural pressure allows for the fluids the rise within the drill used in extraction.

How are they used

Coal and gas are used to power electrical generating plants. They are used to heat steams which drives turbines and produce electricity.

Natural gas is used as a domestic fuel for cooking and so also coal.

When crude is processed a lot of product is obtained. Gasoline is used to power most internal combustion engines. Some chemicals useful for manufacturing plastics, drugs e.t.c are also derived from the processed crude.

How do leaves help with cellular reputation ?

charle [14.2K]

Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars...Respiration occurs when glucose combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal functions.

The distance between two charges and is r, and the force between them is F. What is the force between them if the distance betwe

dimulka [17.4K]

The force between them if the distance between them is doubled is a. F/4

Explanation:

To find the answer, we can use Coulomb's law where it is defined as the force between two point charges is directly proportional to the magnitude of the point charges and proportional inversely to the distance between them.

The equation can be written as, $F= K \frac{ q_{1} q_{2} }{r^{2} }$ where k is the Coulomb constant, $q_{1} q_{2}$ are the point charges, and r is the distance between these two point charges.
To find the answer to this question, just substitute 2r in the place of r hence, you will get $\frac{F}{4}$ as the new force when the distance is doubled.
