WebJan 27, 2016 · 12. Okay so after reading various books on sign conventions for work. I am told by my teachers that in chemistry,work done on the system is positive while work done by the system is negative while in physics it's the exact opposite. I only use the former convention. And modify the first law of thermodynamics so that i can work with physics ... WebMany texts use this definition of work, and not the definition based on internal pressure, as the basis of the First Law of Thermodynamics. This definition reverses the sign conventions for work, and results in a statement of the first law that becomes \(\text{Δ}\mathit{U}=Q+W\).) inamood review https://makcorals.com
