2. Energy can change from one form to another. This is called an energy conversion or energy transformation.
• The Law of Conservation of Energy states that energy can change form, but it cannot be
created or destroyed. Therefore, the total amount of energy stays the same.
• In energy transformations, some energy is always lost to the environment as thermal energy.
Examples of energy transformations and their uses:
· A television changes electrical energy into sound and light energy.
· A toaster changes electrical energy into thermal energy and light.
· A car changes chemical energy from fuel into thermal energy and mechanical
energy.
· A flashlight changes chemical energy from batteries into light energy.
· Solar energy is converted into electrical energy using solar panels.
· Campfires convert chemical energy stored in wood into thermal energy, which
is useful for cooking food and staying warm.
ahmrf....
well a good definition is solar energy
Chemical energy transformations in a cell involve processes like glycolysis, the citric acid cycle, and oxidative phosphorylation. These pathways convert nutrient molecules into ATP, the cell's main energy currency. ATP is then used to power various cellular activities like metabolism, growth, and reproduction.
There are no tidal wave power stations.Tidal waves are unpredictable. There is no way at present to capture their energy. We can capture the energy of tides and also of waves, but not of tidal waves.
In the chloroplast, light energy is transformed into chemical energy during the process of photosynthesis. This chemical energy is stored in the form of glucose, which can be later used by the plant for cellular respiration to produce ATP for energy.
In most energy transformations, part of the energy is wasted. Much of the wasted energy is usually converted to heat.
The byproduct of energy transformations is heat, which is released into the environment. This is due to the second law of thermodynamics, which states that some energy will always be converted into an unusable form (in this case, heat) during energy transformations.
Electrical energy to kinetic energy
from electrical energy to mechanical energy
There are a few energy transformations when a gun is fired. Some of these include potential to kinetic energy, chemical to mechanical energy, and chemical to electromagnetic energy.
Kinetic and potential energy are common types of energy involved in energy transformations. Kinetic energy is associated with the motion of objects, while potential energy is associated with the position or state of an object. These energies can be converted from one form to another during energy transformations.
During energy transformations, energy is never created or destroyed, but it can change from one form to another (e.g., thermal to mechanical).
