Learning goal 3: Identify which fuels are burned as a source of energy.CoalNatural gasNuclear fuelPetrol

All the fuels mentioned - Coal, Natural Gas, Nuclear fuel, and Petrol - are burned as a source of energy. Here's a brief explanation of each:

1. Coal: This is a fossil fuel that is burned to generate electricity. It is one of the largest sources of energy in the world. When coal is burned, it releases energy, which is used to heat water, creating steam that drives a turbine connected to a generator.

2. Natural Gas: This is another fossil fuel that is often burned to produce electricity, heat buildings, and power vehicles. It is cleaner than coal and is abundant.

3. Nuclear Fuel: This is a bit different. Instead of being burned, nuclear fuel (like uranium or plutonium) undergoes a process called nuclear fission in a nuclear reactor. This process releases a large amount of heat, which is used to generate steam and drive a turbine connected to a generator.

4. Petrol: This is a liquid fossil fuel that is primarily used to power vehicles. When petrol is burned in an engine, it releases energy, which is used to move the vehicle.
