First Law of Thermodynamics: Law of Conservation of Energy

WebThe work done by the gas is equal to negative the work done on the gas because if the gas does 100 Joules of work that's, like, someone doing negative 100 Joules of work on the gas. Because if you do negative work on an object you're actually taking energy away from it. So, that's the first law of thermodynamics. WebThe First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed. It can, however, be transferred from one location to another and converted to and from other forms of energy. rccb hager
