Question

How does hess's law follow the first law of thermodynamics?

Answer 1

Hess's law is based on the first law of thermodynamics which says that energy cannot be created or destroyed but can be converted from one form to another. Hess's Law of Heat Summation states that the enthalpy change for a reaction is the same whether it occurs by one step or by any (hypothetical) series of steps.

Answer 2

• Hessa's law basically depends on the conservation of thermal energy. and this is how it follows the first law of thermodynamics as well.
• Both the laws state that the total energy of the system where any chemical reactions or any action is going on will remain constant throughout the process.
• It states that energy will be finite and will neither get created nor destroyed in any action or process.
