15 Example Of Chemical To Mechanical Energy: Detailed Explanations

In this article, we will discuss the various example of chemical to mechanical energy conversion techniques used in our daily lives in detail.

Here is a list of examples that we are going to discuss in this topic:-

Batteries Used in Drones

The chemical energy received from the batteries is converted into the mechanical energy used for rotating the propellers on the drone.

The trust required for a drone to take a lift in the vertical direction depends upon the mass and dimension of the propellers, the acceleration of the motors, and also the power supply from the batteries.

Water Turbines

The water turbine derives the potential energy and the kinetic energy of the moving water by converting it into mechanical energy.

This has a rotating shaft that runs based on the direction of flow of volume of water and then increases its speed.

Toy Cars Running on Batteries

The batteries used in toys supply the chemical energy to the motors on the toy car to accelerate. Hence, this is also an example of the conversion of chemical energy into mechanical energy.

Hydrogen Fuel

Hydrogen fuel is a green fuel and environmentally friendly fuel, releasing no harmful chemicals in the atmosphere and producing a large amount of energy.

This has various uses and can also be used in different vehicles and rockets, and even in highly reactive substances, by converting its chemical energy into mechanical energy.

Filling a Balloon with Helium Gas

Helium is a lighter chemical element and is an inert and non-toxic gas. Filling the balloons with helium gas tends to blow the balloon, if released after blowing, it will produce a whistling sound as air comes out from it thus moving like a rocket here and there until the gas blown in it leaves entirely. This is a form of mechanical energy.

The balloons filled with helium gas easily sway away in the air and will always rise above the level of the atmosphere.

Flow of water carrying sediments

The flowing water has a lot of chemical potential energy that results in the degradation of the sediments into a fine powder and even carries the sediment along with the sediments and dumps them down the cliff, depositing them making a sedimentary rock basin.


Steamboats works on steam engines, that consist of a boiler that produces steam to derive the mechanical energy to drive a steamboat. The steam engine controls the expansion and compression of the steam produced from the boiler.



The blender converts chemical energy to electric energy which is then converted into mechanical energy by rotating the blades attached to the shaft.

Diesel in Vehicles

The vehicles receive energy from diesel. Every vehicle has an efficient engine at needs fuel for the supply of chemical energy. The engine helps to convert chemical to mechanical energy.

The diesel engine works in 4 strokes, first is an intake stroke where the air gushes in as soon as the piston moves up creating low pressure. After this, the air is compressed when a piston moves from up to down position spontaneously called a compression stroke, where the air is heated up. Then comes a power stroke where again the piston is moved upward and fuel is burned due to combustion supplying power to the vehicle.

Finally, the exhaust gases are drawn out from the cylinder to the exhaust valve by an exhaust stroke by pushing the piston upward. This results in the motion of the wheels of the vehicles.


The burning coal supplies energy to the engine through combustion reaction. Thus the chemical energy gives heat energy which is then converted into the mechanical energy required for the engine of a train to work.

Thermal Power Plants

Nuclear fission gives out an immense amount of energy. This energy is also utilized to run the turbines which are then used to convert this mechanical energy produced into electric energy.

Uranium fuels are mostly used in nuclear power plants.

Physical Activities

Food supplies a lot of chemical energy that is stored in our body in the form of potential energy which is then converted into mechanical energy when we are doing some activities like walking, running, jumping, pulling, pushing, etc.


The clocks have a battery. The chemical energy derived from the batteries is supplied to a motor that runs thus converting chemical to electric energy first and then this motor runs the gears on the clock mechanism that causes the hands of the clock to move by converting electrical energy in the form of mechanical energy.

Gunpowder is used to supply the mechanical energy to the bullet on firing. The chemical energy of the gunpowder is turned into heat energy and then to the mechanical energy to the bullet.


The firecrackers come with the highly reactive chemical powder that upon ignite makes a blast heat the system.

The ejection of the missiles or the containers causing the explosions in the upward direction is because the heat released gives out the mechanical energy to the missiles.


A lot of energy is required to lift the rocket into space making an upwards thrust.

This energy is supplied to the rocket by the chemical injected into its body. The fuel is ignited to produce a high amount of heat energy enough for it to take its flight vertically with very high speed.

Frequently Asked Questions

What is chemical energy?

The chemical energy is derived from the chemical reaction.

The chemical energy is stored by the molecules and atoms constituting the bond and releases energy when these bonds break.

How chemical energy is converted into mechanical energy?

There are different methods for the conversion of chemical energy to mechanical energy.

The energy released from the chemical can be directly used to do mechanical work or it may convert into some other form of energy which is then used to derive the mechanical energy.
