Fuel is a substance that undergoes combustion to produce heat energy. When fuel is burned, the chemical energy stored in it is converted into thermal energy, which can then be used to power engines or generate electricity. Different types of fuel, such as gasoline, diesel, and natural gas, have varying energy densities and are used for different applications.

What is the main fuel for the work of the cell?

The main fuel source for the work of the cell is the mitochondria.


How does viscosity of a fuel oil affect the performance of fuel pump and injector in a diesel engine?

Higher viscosity fuel oil can make it harder for the fuel pump to pump the fuel through the system, leading to increased wear and potential damage to the pump. It can also affect the spray pattern and atomization of fuel in the injector, impacting combustion efficiency and engine performance. Lower viscosity fuel oil is generally preferred for better pump and injector performance in a diesel engine.


What energy sources produces electricity by chemically combining gases or liquids into fuel?

Fuel cells are energy sources that produce electricity by chemically combining gases or liquids into fuel. They work through an electrochemical reaction that converts the chemical energy of the fuel into electrical energy, making them an efficient and clean alternative to traditional combustion-based power generation.


What materials are required for a hydrogen fuel cell?

Hydrogen fuel cells require a few key materials, including a proton exchange membrane, catalysts (often platinum), hydrogen fuel, oxygen from the air, and appropriate electrical connections. These materials work together to facilitate a chemical reaction that generates electricity.


How does a campfire work?

A campfire works by burning fuel, typically wood, in the presence of oxygen. The heat from the initial flame causes nearby wood to reach its ignition temperature, continuing the combustion process. As long as there is a steady supply of fuel, oxygen, and heat, the campfire will continue to burn.
