A car engine converts the heat energy contained in the hot high-pressure gases in the cylinder into mechanical energy. The heat comes from the formation of chemical bonds between carbon and oxygen, and between hydrogen and oxygen, when the hydrocarbon fuel is burnt with the air in the cylinder at the top of each power stroke.

What causes some mechanical energy to change to thermal energy?

Normally, friction between moving surfaces causes mechanical energy to convert to thermal energy (heat), as in the brakes of most cars.


How do motors on hydrogen cars differ from combustion or hybrid engines?

Like a gas combustion engine, a hydrogen engine relies on the combustion process - in this case, combustion that results when hydrogen is combined with oxygen. Fuel cells in a hydrogen-powered car then convert this mechanical energy into electrical energy.

Can car battery convert mechanical energy to electrical energy in cars?

No, car battery can only be charged or recharged. The process of energy convertion is done by the generator/dynamo included in the car motor.


What is a device that converts electic energy?

Here are a few examples: Engines (gasoline, diesel, gas turbine) - Convert chemical energy to mechanical energy. Electric motors - Convert electrical energy to mechanical energy. Wind turbines - Convert the kinetic energy of wind into mechanical energy (which is then commonly turned into electrical energy by a generator hooked to the turbine). A light bulb - Turns electrical energy into light and heat. A wood stove - turns chemical energy into heat (and a bit of light) A roller coaster - converts back-and-forth between potential energy (the cars high on a hill) to kinetic energy (the cars going fast). A solar cell - Turns light into electricity


What is the internal combustion engine needed for?

The internal combustion engine is used in almost everything that needs power or motive traction. Cars, trucks, motorcycles, boats, ships, aircraft, and many other things use internal combustion engines. The internal combustion engine is needed to convert fuel chemical energy to rotational mechanical energy, which can now be used for many different applications.


Does a car convert gas into energy using an endothermic reaction?

The energy release is exothermic although the exothermic reaction is not the goal. The goal is rapid expansion of gases in order to move the pistons away from the cylinder head. Heat is a by product....and an unwanted one at that.


What are examples of chemical energy being transformed into mechanical energy?

The (auto) engine found in many cars. Fuel is burnt (chemical change resulting in heat) and converted to mechanical energy (through the action of the pistons and crankshaft). Explode or burn the chemicals, e.g gasoline engine burns gas (petrol) and turns the energy into mechanical energy.


Do electric cars have an engine, and if so, how does it differ from traditional gasoline engines?

Electric cars do not have a traditional internal combustion engine like gasoline cars. Instead, they have an electric motor powered by a battery. This motor converts electrical energy into mechanical energy to drive the car, making it more efficient and environmentally friendly compared to gasoline engines.


What type of energy source is gasoline?

Gasoline is a Mechanical energy because gasoline can make cars move and cars are moving things.
