chemical energy and its converted to kinetic energy
13J energy is stored in petrol,
Chemical potential energy is stored in petrol. When petrol is burnt, this chemical energy is converted into heat, light, and mechanical energy to power vehicles.
No, petrol is a form of stored chemical energy. When burned, it releases heat energy which can be used to perform work.
A liter of petrol contains approximately 31,536,000 joules (or about 31.5 megajoules) of energy. This value can vary slightly depending on the specific composition of the petrol, but it provides a general estimate of the energy content. This energy is released during combustion, making petrol a significant source of energy for vehicles and machinery.
When doing a comparison to petrol for math coursework you could compare the cost of petrol energy to the cost of electrical energy. For instance, camparing operating cost of a vehicle that runs on petrol verses a vehicle that runs on electric energy.
A petrol chainsaw converts chemical energy stored in gasoline into mechanical energy through combustion.
Standard petrol has an energy content of approx. 9.67kWh/liter (34.8MJ/liter)
Petrol and kerosene oil are both fossil fuels that contain chemical potential energy. When burned, these fuels release energy in the form of heat and light.
