Transfers thermal energy to move pistons that provides power?

This describes a heat engine, such as an internal combustion engine. Thermal energy is converted into mechanical energy, which drives the movement of pistons to generate power.

Why can nitrogen and oxygen combine inside a car engine?

Nitrogen and oxygen can combine inside a car engine due to the high temperatures reached during combustion. This leads to the formation of nitrogen oxides (NOx) as a byproduct. Nitrogen and oxygen in the air react with each other under these conditions to produce NOx emissions.

How is fossilfuel energy transformed into usable energy?

Fossil fuel (coal, crude oil) is burned or distilled to provide a usable energy. Either as a diesel or petrol fuel for an internal combustion engine, or to heat water to provide steam power.

Where can someone find more information on search engine optimisation?

The help functions available on an engine site can provide additional information on optimizing use of the engine. This may include tips on the use of operators to combine search terms and punctuation to require specific search language.

What does jerking and losing power during acceleration mean?

it means there is something wrong with the spark plugs cause they provide the energy for the engine

What two substances causes an exothermic reaction?

Many substances can "cause" (or participate in) exothermic reactions. An exothermic reaction is a reaction that gives off thermal energy, as opposed to an endothermic reactionwhich requires the input of energy to occur. A classic example of an exothermic reaction is the burning of gasoline in an automobile engine. Gasoline is ignited to induce an exothermic combustion reaction with free oxygen in the air. The reaction causes the release of thermal energy which is converted to mechanical energy as the resulting gasses expand inside the engine's combustion chamber. Excess thermal energy is also released into the cylinder walls of the engine. So much so that your car has a coolant system just to absorb the excess thermal energy into a water-based coolant, and dissipate it from your radiator. Lots of heat energy being given off=exothermic reaction. And again, there are many different exothermic reactions involving many different substances.

What is a torsion engine?

A mangonel is the perfect example of a torsion engine. The drive provided to this ancient catapult comes from a mass of twisted ropes which create torsion and when released provide the energy required to hurl whatever it is you wish.

Function of the battery?

The function of a battery is to provide electrical energy to devices which are connected to it.

What type of energy is converted to energ of motion in an internal combustion engine?

In an internal combustion engine, the provided energy is chemical energy. By means of combustion it is transformed into heat energy. This heat energy is transformed in to motion/kinetic energy in an internal combustion engine.
