1.Thermodynamics Thermodynamics is the branch of physics that deals with the relationships between heat, work, and energy. It describes how thermal energy is converted to and from other forms of energy and how it affects matter. 2. Laws of Thermodynamics There are four laws of thermodynamics: 1⃣ Zeroth Law: If two systems are in thermal equilibrium with a third system, then they are also in thermal equilibrium with each other. 2⃣ First Law: Energy cannot be created or destroyed, only converted f
