Thermodynamics Thermodynamics is the branch of science that studies the relationships of heat, work, energy, and pressure. In thermodynamics, it studies the interaction in relation to two kinds of systems: an isolated system and an open system. In an isolated system, material and energy of an object cannot exchange with its environment. In an open system, material and energy can exchange with its environment.
Both this systems are precisely defined regions or spaces under study. Everything else outside the system is known as the surroundings. A boundary separates the system and the surroundings. Laws of Thermodynamics There are four laws that govern the behavior of energy and the passing of energy in thermodynamics. The Zeroth law: When 2 systems are in thermal equilibrium with a third system, these 2 systems are in thermal equilibrium with each other. Heat Transfer As with the laws of thermodynamics, the transfer of heat between one object to another is defined by these. Thermodynamics & statistical mechanics.
