38
Q

Generation of Electrical Energy from Coal

A

Burning Coal: Coal is burned in a big furnace to produce a lot of heat.
Boiling Water: The heat is used to boil water, turning it into steam.
Creating Pressure: As the water turns to steam, it builds up pressure in the boiler.
Spinning the Turbine: The high-pressure steam is directed onto a steam turbine, which spins because of the steam’s force.
Generating Electricity: The spinning turbine is connected to a generator. Inside the generator, a magnet spins, creating electricity.
Sending Electricity: The electricity produced is sent to the power grid, which delivers it to homes and businesses.

A

natural gas

45
Q

thermogenic or organic thermal maturation. It begins with the accumulation of organic material, such as dead plants and microorganisms, in oxygen-depleted environments like swamps and seabeds.

A

thermogenic or organic thermal maturation

46
Q

Over time, sediment accumulates over these organic deposits, creating pressure and heat due to the weight of the overlying layers. As temperatures and pressures rise, the organic material undergoes a series of chemical reactions known as _________________

A

thermal maturation.

47
Q

During this process, complex organic molecules break down, forming simpler hydrocarbons like methane (CH4). These hydrocarbons migrate upwards through porous rocks until they are trapped by impermeable layers, forming reservoirs of natural gas beneath the Earth’s surface. The extracted gas is a valuable energy source used for heating, electricity generation, and various industrial processes.

A

Natural gas

52
Q

Generation of Electrical Energy from
Natural Gas

A
  1. Burning Gas: Natural gas is burned in a machine called a gas turbine.
  2. Spinning the Turbine: The hot gases produced from burning the gas make a turbine spin.
  3. Generating Electricity: The spinning turbine powers a generator, which turns the motion into electricity.
  4. Distributing Power: The electricity is then sent through power lines to homes and businesses.
    Natural gas power plants are efficient and produce less pollution compared to coal or oil plants.
