In Rudbeckia hirta, commonly known as black-eyed Susan, energy transformation primarily involves the process of photosynthesis. During photosynthesis, the plant converts light energy from the sun into chemical energy stored in glucose, using carbon dioxide and water. This transformation supports the plant's growth, development, and reproduction by providing the necessary energy for metabolic processes. Additionally, during respiration, the stored chemical energy is converted back into usable energy for the plant's cellular functions.
What energy transformations take place in:
kinetic energy
A log burning in a fire place.
light energy is changed into chemical energy.
The energy transformation that takes place is the conversion of one form of energy to another, such as kinetic energy to thermal energy, electrical energy to light energy, or chemical energy to mechanical energy. This conversion is governed by the laws of thermodynamics and is essential for all processes and activities in the universe.
When sunlight strikes a house, the energy transformation that takes place is from radiant energy (sunlight) to thermal energy (heat). The house absorbs the sunlight, which then gets converted into heat energy, warming up the interior.
Kinetic energy
transforms from potential energy to kinetic energy =]
Electrical energy is converted into light and heat energy
In the engine of a typical train, the energy transformation that takes place involves converting the chemical energy stored in fuel (such as diesel) into mechanical energy through combustion. This mechanical energy is then used to move the train by powering the wheels.
Chemical energy is turned into heat (kinetic energy) and light (electromagnetic energy).
