First Law of Thermodynamics

First Law of Thermodynamics

Short Description of Topic

The Main Idea

The First law of Thermodynamics states that energy can be neither created nor destroyed. It is also known as the conservation of energy. Even if the energy cannot be created or destroyed, power generation process and energy sources help the conversion of the energy from one form to an another.

A Mathematical Model

{∆U = Q-W} where F U is change in the internal energy ,Q is heat added to the system, and W is the work done by the system.

A Computational Model

Examples

Energy Transformation

By the photo, there is no energy made or destroyed. From eating a piece of chicken that has chemical energy will transform into kinetic energy when riding the bicycle. Also with the light energy of the sun will transform into chemical energy of the plant's leaf. This is an expample of energy transformation.
