The total amount of energy remains the same.
When an energy transformation occurs, the total amount of energy remains constant. Energy cannot be created or destroyed, only changed from one form to another. This principle is known as the law of conservation of energy.
sound energy
Photosynthesis. - the transformation of light energy into chemical energy.
hydrogen fusion
In a firecracker, energy transformation occurs when the chemical potential energy stored in the gunpowder is converted into thermal energy (heat) and light energy (in the form of the explosion and sparks). This transformation happens rapidly and produces a loud sound due to the expanding gases pushing outward.
fire energy
electrical to sound
When coal is burnt, the energy transformation that occurs is from chemical energy stored in the coal to thermal energy in the form of heat, which can be used to generate electricity or heat for various applications.
electical energy is transform to heat energy
When condensation occurs, heat is released into the surrounding environment. This heat is a result of the energy transformation from a gas state to a liquid state, causing the molecules to slow down and release energy in the form of heat.
