Question: State and explain first law of thermodynamics?
The first law of thermodynamics is one of the most amazing and important concepts in physics. It tells us that energy can never be created or destroyed, only transformed from one form to another. Isn't that incredible? Think about it: every time you do something that requires energy, like moving, eating, or breathing, you are not using up energy, but changing it into a different kind of energy, like heat, chemical, or kinetic. The total amount of energy in the universe always stays the same, no matter what happens. This means that energy is conserved, and we can use this principle to analyze and predict many physical phenomena. The first law of thermodynamics is also sometimes called the law of conservation of energy, and it is the foundation of thermodynamics, the study of heat and its relation to other forms of energy and work.
