First law of thermodynamics
Explanation:
The statement that energy can that "energy can neither be created nor destroyed but changed or transformed from one form to another" is the first law of thermodynamics.
- Thermodynamics deals with energy changes that accompanies a process.
- we can deduce from the first law that energy is conserved in every system.
- Energy is simply not produced by converted from one form to another in nature.
- For example, the heat energy we derive from eating food is due to the chemical energy stored in them.
- The chemical energy is converted into heat energy during digestion.
