The First Law of Thermodynamics is the Law of Conservation of Energy - in other words, the total amount of energy in a closed system remains constant.

The first law of thermodynamics states that energy cannot be destroyed or created but is always conserved.


That's related to the First Law of Thermodynamics - the Law of Conservation of Energy.


There are four laws of thermodynamics;Zeroth Law of Thermodynamics.First Law of Thermodynamics.Second Law of Thermodynamics.Third Law of Thermodynamics.



The first law of thermodynamics is the law of conservation of energy. They are the same thing. The first law of thermodynamics states that the energy within a closed system is constant regardless of changes in that system. The law of conservation of mass and energy states that total mass and energy (in a closed system) will always remain the same despite changes inside of the system.


What is the industrial application of first law of thermodynamics?


The first law of thermodynamics


The first law of thermodynamics states that whenever energy is converted from one form to another, the total quantity of energy remains the same.


The First Law of Thermodynamics is another name for the Law of Conservation of Energy.


First Law of Thermodynamics: Energy can be converted from one form to another, but cannot be created or destroyed.Second Law of Thermodynamics: The second law of thermodynamics states that for any process occurring in a closed system, the entropy increases for an irreversible system and remains constant for a reversible system, but never decreases.



It is called the law of conservation of energy, or sometimes the first law of thermodynamics.


The first law of thermodynamics states that energy can be transformed, but not created nor destroyed. In a nuclear reaction, mass is transformed into energy.


That would be the implication of the second law of thermodynamics.




The second law of thermodynamics states that entropy of any reversible reaction is greater than or equal to zero.


That law is known as the Law of Conservation of Energy. It is also known as the First Law of Thermodynamics.


That would be the First Law of Thermodynamics. It is the same as Conservation of Energy.


the first law of thermodynamics also known as the law of the conservation of energy states that energy cannot be created or destroyed during a chemical reaction but can only be transformed or converted from one form to another.


Application of first law of thermodynamics is in engine, refrigerator,heat pump.



First law states that energy can neither be created nor be destroyed. Energy can only be transferred into or out of a system. Equation that defines first law of thermodynamics is dQ = dU + dW .
