Calorimetry

• A fuel is a substance that releases energy when burned
• Combustion is fuel that reacts with oxygen to release energy
• Complete combustion reaction = fuel + Oxygen > Carbon Dioxide + Water
• A fuel is something which burns, releasing energy as light and heat.
• Fuels are also used in power stations to make electricity.
• When fuels burn out of control, they can be very dangerous.
• Coal, gas, and oil fuel the world today.
• Coal is a rock which burns, made of ancient plant material from 300 million years ago when most of Britain was covered by huge tropical forests.
• Natural gas and oil are the fuels we use the most
• Solid fuel is the safest to carry and is lightweight but it burns slowly and is a bit smoky.
• Universal indicator changes from green to red when burning coal.
• When fuels burn, they react with oxygen in the air, and all fossil fuels contain carbon and hydrogen, so new chemicals are produced.
• Lime water goes milky when carbon dioxide is produced
• Liquid fuels may be burned in a spirit burner. We can weigh the burner before and after to find out how much fuel has been burned
• Methanol = CH4
• Button = C4H9OH
• Erhanol = CH3CH2OH
• Propan = CH3CH2CH2OH
