The process of burning gas in a car engine to release what kind of energy physical or chemical?

Neither, the process of burning gas (which stores chemical energy) releases that energy as "HEAT" energy. This heat energy is then converted into mechanical energy.


What is the process used to extract energy from combustible fuels?

Combustion is the process of burning a fuel to release its energy. In an engine or power plant, the fuel is ignited and the heat generated is used to produce mechanical work, such as turning a turbine or piston, which in turn generates electricity. This process is efficient in converting the chemical energy in the fuel into useful work.


Is burning petrol in a car engine exothermic or endothermic?

Burning petrol in a car engine is an exothermic process because it releases heat energy. The combustion of petrol with oxygen produces carbon dioxide, water vapor, and heat as byproducts, which powers the engine.


What source of energy does an internal combustion engine use steam hot water burning fuel or refrigerant?

Burning fuel.Burning fuel.Burning fuel.Burning fuel.


Is burning petrol in a car engine exothermic?

YES!!! DEinitely!!!!! By the simple fact that the car engine becomes hot, when the engine is running (burning petrol). Petrol is a hydrovarbon. When combusted in a car engine, it is a chemical reaction between the hydrocarbon (petrol) and oxygen(air). This chemical reaction is exothermic, ( releases energy/heat). This release of energy is done in a very small space, hence the hot expanding gases push the piston down, and thereby mechanically move the car. The heat energy that you feel is waste energy. However, this 'waste' energy is used to heat the car interior. Here is a chemical word equation hydrocarbon + air =electric spark-> Carbon dioxide + Water. Hope that helps!!!!!


What process converts chemical energy to a mechanical energy?

An engine is needed to do this. A steam engine A jet engine A car engine A battery driven electric engine. The process is normally multi step.


What do you get from natural gases?

By burning natural gas in a combustion engine, you get mechanical energy.


What source of thermal energy does an internal combustion engine use?

burning fuel


How did energy make a car go down the street?

The energy generated from burning fuel in the engine is converted into motion to move the car down the street. The fuel combustion creates mechanical energy that is transferred to the wheels, propelling the car forward. This process is facilitated by the complex system of the car's engine and drivetrain.


New car burning smell?

The new car burning smell is probably just the oils burning off the engine. As the engine warms up for the first time, it will release a odor that smells like something is burning.


What does burning fossil fuels and cellular respiration have in common?

Both release carbon into the atmosphere, but burning fossil fuels releases CO2 at a much greater amount. Both cellular respiration and combustion require a core fuel for the process to happen at all. This fuel is stored energy, and the entire process of combustion or respiration is to convert that energy from its stored state -- in the fuel -- to another state that the engine, either mechanical or bionic, can use to power its other operations. While fossil fuels and sugar molecules have very different structures, they both have a series of molecular bonds that the energy harvesting process will break apart.


Which energy transformation takes place in a gasoline engine?

In a gasoline engine, chemical energy from burning gasoline is converted into mechanical energy as the engine's pistons move up and down. This mechanical energy is then used to power the vehicle and overcome friction and other forces.
