WebThe first law is a statement of energy conservation. It tells us that a system can exchange energy with its surroundings by the transmission of heat and by the performance of work. The net energy exchanged is then equal to the change in the total mechanical energy of the molecules of the system (i.e., the system’s internal energy).

WebThis occurs when the systems are at the same temperature. In other words, systems at the same temperature will be in thermal equilibrium with each other. The first law of thermodynamics relates changes in internal energy to heat added to a system and the work done by a system. The first law is simply a conservation of energy equation: WebSolar energy has seen the second-highest growth, just behind wind energy, rising from only 1.21bn kilowatt hours (KWh) in 2010 to 114.68bn KWh in 2024.
