Burning fossil fuel takes free oxygen from the air. In a car, air, which includes free oxygen, comes into the engine through an air filter and the air is then mixed with fuel and sent to the engine. The fuel-air mixture is ignited, gets hot, its pressure rises and this drives down a piston that drives the crankshaft.
The fuel contains carbon and hydrogen, and the burning process unites carbon with oxygen, and also hydrogen with oxygen. Both these chemical process produce a lot of heat.
The formation of these chemical bonds generates CO2 and H2O, also known as carbon dioxide and water, which are the major products of burning fossil fuel. In round numbers, burning 1 kg of fuel takes 3.5 kg of oxyen from the air, and generates 3.1 kg of CO2 plus 1.4 kg of water; and about 50 MJ of heat energy is generated.
In the average car engine, about 25% of the heat energy produced is converted into mechanical energy to drive the car.
things such as cars plans and certain factories burn fossil fuels
The pollution from the cars is hazardous to the air quality from fossil fuels. Fossil fuels have to burn a lot of gas and coal in order for cars to get driving.
A disadvantage of fossil fuels is that when you burn them to create energy, it pollutes the air. An advantage of fossil fuels is that we use them to power cars and many other things.
Burn less fossil fuels
Energy led human to burn more fossil fuels
All cars use fossil fuels somewhere in their energy cycle.
they burn fossil fuels like coal, fuel oil, and oil shale
Yes they do!
no
No. Most cars use fossil fuels (primarily gasoline and diesel made from oil).
burn fossil fuels or turbines or hydro or wind
We should not burn fossil fuels.
