explain 1st law of thermodynamics?
Answers
The first law of thermodynamics is also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system.
The 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.
First Law of Thermodynamics Equation
The equation for the first law of thermodynamics is given as;
ΔU = q + W
Where,
ΔU = change in internal energy of the system.
q = algebraic sum of heat transfer between system and surroundings.
W = work interaction of the system with its surroundings.
