| Law Of Conservation Of Energy |
|
|
Law of Conservation of Energy states that in a chemical
reaction, the total amount of energy in the system remains unchanged.
Energy can be transferred from one form into another but cannot
be created or destroyed. |
|
|
The forms of energy includes kinetic and potential energy as well as light, heat and sound. Energy can also be transferred between objects. |
|
|
Since energy cannot be created or destroyed, the amount of energy present in the universe is always the same. It is simply being transformed and transferred over and over again.
|
|
|
If you have a reaction in a closed system, the total energy at the beginning will be the total energy at the end.
|
|
|
For example, the chemical energy of a battery is transferred
into the electrical energy in a circuit, which can then be transferred
into the heat and light energy of a bulb, but the total amount
of energy is constant. |
