We have not used the word ‘burn’.
This is because in everyday language it does not have
a precise meaning. For example,
If we leave a cake in the oven too long so we are left
with charcoal, we say ‘we have burnt the cake’.
A scientist would say this is an example of decomposition.
For a gas cooker flame, we say ‘the gas is burning’.
A scientist would say that this is an example of combustion.
These are two quite different reactions and in science
one word won’t really do for both!
