why do we burn fuels 9h task sheet

We burn fuels to produce energy. When these fuels burn, the
atoms An atom is the smallest part of an element that still has the properties of that element, comprising electrons surrounding a nucleus of protons and neutrons. molecules a collection of two or more atoms held together by chemical bonds.


The fundamental unit of compounds. Coal is made mainly of carbon. This burns to produce carbon dioxide. Petrol, diesel fuel and fuel oil are hydrocarbons. Their molecules are made of carbon and hydrogen atoms.


When these fuels burn, the carbon and hydrogen atoms combine with oxygen atoms to produce carbon dioxide and water vapour. An introduction to combustion for KS3. The lesson requires a setup for the detection of the products of combustion - with CoCl2 paper and lime water, and a practical investigating the amount of oxygen used up in combustion (measured as the volume of water sucked up inside the beaker when put at the top of the burning tea candle - placed in the trough filled with water).


This follows by the data analysis and the task comparing the incomplete and complete combustion.


The plenary is based on the dangers of carbon monoxide poisoning. Please leave me with a star rating or write a comment if you find this useful.
