Answer 1

Example 1: Energy transformation from Chemical to Light
When a firework is ignited, the combustion of chemicals within the firework results in an energy transformation from chemical energy to light energy. The chemicals contained within the firework, such as gunpowder or explosive compounds, release stored chemical energy when ignited. This energy is transformed into the production of intense light that we observe as the firework explodes and produces a beautiful display of colors and patterns in the night sky.

Example 2: Energy transformation from Electrical to Heat and Light
When an incandescent light bulb is turned on, an energy transformation occurs from electrical energy to both heat and light energy. The electrical current flowing through the filament of the light bulb encounters resistance, resulting in the production of heat. Simultaneously, this electrical energy is transformed into light energy, allowing the bulb to emit illumination. Therefore, as the light bulb is turned on, the electrical energy supplied to it is converted into both heat and light energy.

Example 3: Energy transformation from Chemical to Mechanical
In a car engine, an energy transformation takes place from chemical energy to mechanical energy. When the car's engine is fueled with gasoline, the internal combustion process occurs. The burning of the gasoline releases stored chemical energy, resulting in the generation of high-pressure gases. These gases exert force on the engine's pistons, causing them to move up and down. The reciprocal motion of the pistons is then transferred to various mechanical components, such as the crankshaft, which further translates the reciprocating motion into rotational motion. Ultimately, this energy conversion from chemical to mechanical allows the car's wheels to turn and propel the vehicle forward.

Example 4: Energy transformation from Light to Chemical
During photosynthesis, energy is transformed from light energy to chemical energy. Plants possess specialized pigments, such as chlorophyll, which are capable of capturing sunlight. When sunlight interacts with these pigments, a series of chemical reactions occur, converting light energy into chemical energy stored within molecules such as glucose. This transformed chemical energy is then utilized by the plant to carry out essential processes, such as growth, reproduction, and cellular respiration.
