Petrol has a higher value of the heat of combustion.
All balloons expand in heat.
Heat makes gas expand. When gas is heated, its molecules gain energy and move faster, increasing the pressure and causing the gas to expand in volume.
When petrol burns, chemical energy stored in the molecules of petrol is converted into heat and light energy. This is a result of the combustion process, where the carbon and hydrogen in petrol react with oxygen to form carbon dioxide and water, releasing energy in the form of heat and light.
No, although it does expand with heat as do most substances.
