1.A fossil fuels

Fuel

A substance with stored energy that can be released relatively easily for use as heat or power

International system of units (SI units)

Joules (J)

Non-renewable

Sources cannot be replenished by natural processes within a relatively short period of time

Fossil fuel formation

Formed from the decomposition of buried dead organisms. The absence of oxygen, heat and pressure alter the chemical structure of the organic matter.

Coal energy potential

Amount of water within coal determines its energy potential. Black coal: 90% carbon: 34kJ/g

Complete combustion reaction (equation)

Fuel+oxygen gas → carbon dioxide + water + energy

Incomplete combustion reaction equation

Fuel+oxygen gas → carbon monoxide +/ carbon + water + energy

Combustion reaction type

Exothermic redox
