Thermodynamics — First Law flashcards

6 formula cards covering every form of the First Law of Thermodynamics — ideal for GATE, JEE and NEET revision.

First Law of Thermodynamics (General Statement): ΔE_system = Q − W
For a Closed System (No Mass Transfer): ΔU = Q − W
For an Open System (General Form): steady flow energy equation
Steady Flow Energy Equation (Simplified): Q − Ws = ṁ(h_out − h_in)
Adiabatic Process (No Heat Transfer): Q = 0 ⇒ ΔE_system = −W
Differential (Rate) Form: dE_system/dt = Q̇ − Ẇ
