Thermodynamics is the study of processes involving changes in temperature and transformation of energy[1]. It is also important in describing the relationships between heat and work. It can be used as an engineering tool for describing power and energy systems.
There are 3 laws of thermodynamics:
- The first law states that energy can neither be created nor destroyed. This law states that the energy contained within the Earth always has and always will remain constant.
- The second law states that entropy, which the level of disorder within a system or the tendency for things to move from a level of order to disorder, always increases as energy types are converted (e.g. heat to kinetic)[2].
- The third law of thermodynamics states that in a perfect crystal at 273K also known as absolute zero, the entropy is 0[3].
