Thermodynamics is the area of physical science that deals with heat and how it relates to other forms of energy. Scientists who study thermodynamics observe how heat—or thermal energy—converts into other forms of energy and how it interacts with matter. If you study thermodynamics, you're looking at the properties of heat, temperature, and conductivity and how all three react in different environments. When you conduct an experiment in thermodynamics, you're making large scale observations on the relationship between heat, temperature, and work with mechanical energy, chemical energy, electrical energy, and other forms of energy.‎
