15 Example Of Chemical Energy To Kinetic Energy:Detailed Explanations


Some chemical compounds are essential to cause the motion of the object. The chemical energy transforms into kinetic energy; some example of chemical energy to kinetic energy are listed below.

Detained explanation on the example of chemical energy to kinetic energy

The motion caused due to a chemical reaction is regarded as a chemical to kinetic energy conversion. Here we will give a brief explanation of an example of chemical energy to kinetic energy.

Gasoline in automobiles

Gasoline is the byproduct of petroleum, a mixture of volatile liquid hydrocarbons widely used in vehicles as fuel for the internal combustion.

The internal combustion of gasoline in the engine is converted into heat by expanding the gas through a linear piston. This heat generated in the piston is responsible for the motion of automobiles. Thus the chemical energy is converted into kinetic energy in automobiles.

Airbags of the car

We are aware of the airbags in the car, which are used as a safety precaution. But have you ever thought that airbags are the best example of chemical energy to kinetic energy?

Well, airbags contain a compound called sodium azide. When this chemical compound is ignited, the airbag activates by filling the nitrogen gas inside the bag; thus, chemical energy is transformed into kinetic energy.

Dry cell

If we connect the dry cell to a motor, the chemical energy is converted into kinetic energy as the motor begins to run.

The dry cell is made up of ammonium chloride, manganese dioxide, zinc anode, and carbon cathode. When the motor consisting of a rotor is attached to the dry cell, the chemical substances react and make the rotor spin very fast. Thus the chemical energy transferred to the rotor, causing the spin kinetic energy.

Explosion of dynamites

A powerful explosive called nitroglycerin is used in dynamite used to demolish buildings and heavy rocks.

When the dynamite explodes, the chemical energy is transferred to the object, causing destruction. Thus the chemical energy is converted into kinetic energy.

Fire Crackers

Firecrackers are good example of chemical energy to kinetic energy when it is burnt. Crackers are filled with the mixture of charcoal, sulfur and potassium nitrate as combustible substance.

When the firecrackers such as sky shots and rockets are burnt, the crackers move upwards and explode. It is due to chemical energy in the crackers being converted into kinetic energy, causing the fire crackers’ vertical motion.

Steam engines of marine boats

Steam engine in marine boats converts chemical energy into kinetic energy, as steam is produced due to burning the coal to boil the water in large boilers.

When the steam is generated as pumped through a pipe towards the piston causes the piston to move upward, creating the required amount of pressure. The pressure thus created forces the boat to move.

Burning charcoal in trains

Burning the charcoal to move the train requires steam. As long as the boiling water generates steam, the train will move.

The combustible substances such as charcoal, oil and rare woods are burnt to fuel the train engine. The driving wheel is connected to the piston, which is pushed by the steam produced by burning the charcoal. Thus the moving trains are excellent example of chemical to kinetic energy.

Helium balloons

Helium is an inert gas. It is lighter than the air and doesn’t react readily with the other elements in the atmosphere; hence, they are used to filling the balloons.

Fill the balloon with helium gas and then release it; the balloon moves vertically in the air making the whistling sound. In this case, the balloons possess kinetic energy when it is released from the chemical energy of the helium gas.

Water turbines

Water turbines are widely used for the generation of electricity from the falling water. Since water is a composition of oxygen and double hydrogen, it has chemical energy.

When the waterfalls on the large turbines from a certain height, the force of water makes the turbine rotate which possesses kinetic energy; thus, chemical energy is responsible for the turbine to possess kinetic energy. Hence water turbine is regarded as an example of chemical energy to kinetic energy.

Drone batteries

Drones are flying robots controlled by the remote. The energy required for the drone to fly is provided by the batteries, which can store the chemical energy in it.

When the drones are switched on, the chemical energy stored inside the batteries provides sufficient energy for the propellers to rotate, which causes the drone to fly high. Thus the chemical energy of the batteries transformed as kinetic energy in the drones.

Kid’s toy

Certain kid’s toys are fitted with batteries of lithium and alkaline. When the toys are turned on, the chemical energy of the batteries provides sufficient energy to work. Thus causing the motion of the toys, so that can be monitored by using remote sensors. Hence the chemical energy of the batteries is converted into kinetic energy of toys.

The remotes are also fitted with batteries. Generally, lithium batteries are used often, as lithium batteries are more efficient compared to the alkaline batteries.

Food digestion to do physical activities

We need the energy to walk or move things. This energy is provided to our body by digesting the food we eat.

As the food is digested, it is stored in our body as chemical energy. When we need to move things, the chemical energy stored in the body is transferred to that object as kinetic energy. While we walk, stored chemical energy possessed by the body is converted into kinetic energy.

Bullets in the firearm

When the firearm is triggered, the gunpowder explodes and makes the bullet leave the gun and move away. Thus chemical energy of the gunpowder is transferred to the bullet as kinetic energy.

Hydrogen fuels

An environmental friendly example of chemical energy to kinetic energy conversion is hydrogen fuel vehicles. Hydrogen fuels are clean fuels with zero-carbon contamination.

The hydrogen fuel-consuming vehicles are fitted with a cell that stores the hydrogen as fuel. The combustion process provides the required amount of energy for the cars to be in motion. The left hydrogen combines with oxygen to form water.

Batteries used in clocks

The lithium batteries of the clocks convert chemical energy to kinetic energy. The batteries provide sufficient energy for the needles of the clock to move. Thus the chemical energy of the batteries is transferred to the needle to possess kinetic energy.

Rocket launch

For a successful rocket launch, the combustion of many fuels has to be burnt. Liquid hydrogen, aluminum fuel with ammonium perchlorate, is used as an oxidizer mixed with binders serves are propellant. Hydrogen is the primary fuel of the main engine.

High pressure is created when the fuel is burnt, which pushes the rocket to move vertically. As fuel goes on burning, the pressure is also increasing, and thus, the acceleration of the rocket also increases to escape away from the earth’s gravity. Thu fuel combustion is responsible for the launching process. Hence, the chemical energy of the fuel is converted into the missile’s kinetic energy.
