Limitations of 1 law of thermodynamics
Nettet24. jan. 2024 · A major limitation of the first law of thermodynamics is that it merely indicates an exact equivalence between the various forms of energies involved in any process. Still, it provides no information concerning the spontaneity or feasibility of the process, i.e., whether the process is possible or not. NettetThe first law of thermodynamics is primarily a restatement of the conservation of energy principle, which claims that energy cannot be created or destroyed. It can only be converted and changed from one form to another. This law applies to all the three phases of matter, i.e., solid, liquid and gas.

NettetWhat are the limitations of the first law of thermodynamics The first law of thermodynamics does not quantify the energy transfer that takes place, failing to explain the feasibility of the thermal process. Stay tuned with … NettetI dag · For a closed system, the first law is written as −. Σ Q = Σ W. But this is only valid for a closed system which is undergoing a cycle. For a process it can be written as −. Q 1 …
