Why do modern cars burn hydrocarbon fuels in their engines?
Hydrocarbon fuels are energy dense, easily transported, relatively cheap.
What is made when hydrocarbon fuels burn?
Co2+h2o
What is the cloud trail from the engines on a high flying airplane?
Basic answer is water vapour from the combustion of the hydrocarbon fuel burnt in the engine. The low temp at high altitude causes the vapour to condense - so it is a man made cloud.All hydrocarbon fuels burn in air (combining with oxygen) to produce water (hydrogen oxide) and carbon dioxide.
What harmful gas is being released when engines burn fossil fuels?
Carbon monoxide is released.
When a fossil fuels is burn energy is converted to kinetic energy?
Fossil fuels represent chemical energy, a form of potential energy. This energy was stored in the hydrocarbon molecules and can be released by oxidation (burning).
Why is it usually difficult to burn different hydrocarbon fuels efficiently in the same appliance?
It is difficult to burn different hydrocarbon fuels efficiently in the same appliance because different fuels have varying compositions, burning temperatures, and combustion characteristics. This can make it challenging to optimize combustion conditions, such as air-to-fuel ratios and flame stability, to achieve efficient and complete combustion across multiple fuel types.
How do hydrocarbon fuels burn in engines?
Its a very complex answer. Here's the short version. Millions of years ago plants absorbed energy from the sun. Those plants got buried and time, pressure and heat turned them into fossil fuels. We clean it up, run it through our engines, where with the proper amount of pressure and temperature the fossil fuel will release the energy stored from the sun millions of years ago and create heat. The process is called combustion. Any hydrocarbon will combust if pressurized (heated) enough. Diesel fuel self ignites when subjected to about 22 to 1 compression. Gas engines assist the initial combustion with a spark plug.
What is produced when hydrocarbon fuels burn inside an engine?
When hydrocarbon fuels burn inside an engine, the products of combustion include carbon dioxide (CO2), water (H2O), and small amounts of nitrogen oxides (NOx) and particulate matter. This process releases heat energy that is used to power the engine.
Why can kerosene and ethanol be used as fuels?
Kerosene and ethanol can be used as fuels because they are combustible substances that release energy when burned. Kerosene is a hydrocarbon fuel that can be easily ignited and produce heat. Ethanol, on the other hand, is a biofuel derived from plant sources which can also be burned to generate energy. Both fuels are commonly used in engines and heating systems.
Name four ways that humans burn fossil fuels?
Some common ways that humans burn fossil fuels include driving cars with internal combustion engines, generating electricity in power plants, heating buildings with furnaces, and using fossil fuels as fuel for industrial processes.
Show the combustion of a hydrocarbon?
It is when you burn Oxygen. Here are equations. Hydrocarbon + Oxygen --> Carbon Dioxide + Water Hydrocarbon + Oxygen --> Carbon Monoxide + Water
