Q. 1st Law of Thermodynamics is normally related to–
✅ Correct Answer: (D)
Law of Conservation of Energy.
Explanation: Heat absorbed by the system i.e ∆Q is equal to the sum of increase in internal energy i.e., ∆U and external work done by the system i.e., ∆W
∴ ∆ Q = ∆U + ∆W
∴ ∆ Q = ∆U + ∆W
Explanation by: Rakesh Yadav
Heat absorbed by the system i.e ∆Q is equal to the sum of increase in internal energy i.e., ∆U and external work done by the system i.e., ∆W
∴ ∆ Q = ∆U + ∆W
∴ ∆ Q = ∆U + ∆W
