Thermodynamic Laws that Explain Systems A thermodynamic system is one that interacts and exchanges energy with the area around it. The exchange and transfer need to happen in at least two ways. At least one way must be the transfer of heat.If the thermodynamic system is "in equilibrium," it can’t change its state or status without interacting with its environment.
