Thermodynamics
Definition
Thermodynamics is the branch of physics that deals with the relationships between heat, energy, and work.
Analogy
Think of thermodynamics as being like a chef in a kitchen. The chef uses heat (energy) to cook food and perform work, such as chopping vegetables. Just like the laws of thermodynamics govern how heat transfers and energy is used in cooking, these laws apply to various processes in nature.

Second Law of Thermodynamics (Law of Increased Entropy): In any spontaneous process, the total entropy (disorder) always increases over time.
Third Law of Thermodynamics: As temperature approaches absolute zero, the entropy approaches a minimum value for perfect crystalline substances.
