Law of Conservation of Energy
The Law of Conservation of Energy states that energy cannot be created or destroyed, only transferred or transformed. This means that the total amount of energy in the universe remains constant, regardless of the transformations energy undergoes.
This law applies to all forms of energy, including mechanical, thermal, and electrical energy. For example, when a car brakes, its kinetic energy is converted into thermal energy, which is then released as heat. The total amount of energy in the system remains the same, even though the forms of energy change.
Here are some examples of how the law of conservation of energy is demonstrated:
When a candle burns, its thermal energy is converted into light and heat.
When a car is driven, its mechanical energy is converted into thermal energy.
When water evaporates, its thermal energy is converted into energy in the form of water vapor
