investigating fuels(unit 3) Flashcards
what do you need to investigate about fuels
how much energy will they produce
what pollutants they produce
how a fuel is chosen for specific purposes, for example, fuelling cars, heating rooms, cooking
fuels you could investigate
petrol food methanol propan-1-ol pentan-1-ol paraffin cooking oil ethanol butan-1-ol wax
is the reaction for combustion exothermic or endothermic
exothermic
fuel+oxygen—->
carbon dioxide + water (+ heat energy)
the longer the carbon chain
the more energy is released during combustion
other factors to consider when choosing fuel
how easy it ignites
how easy it is to store
how easy it is to transport how much /type of pollution it produces
the change in temperature of the water and the change in mass of the spirit burner can be used to calculate?
the heat of combustion of the fuels
