The first law of Thermodynamics is about the conservation of energy and states, “The change in the internal energy of a closed system is equal to the sum of the amount of energy supplied in the form of heat and the work done on the system”. Equation: Du= δQ- Δwwhere δQ is a small amount of heat added to the system, dU is a small increase in the internal energy of the system, and δW is the small amount of work done by the system during the operations of the system. c).

The first law of thermodynamics. 1. Based on graph P-V below, what is the ratio of the work done by the gas in the process I, to the work done by the gas in the process II? Known : Process 1 : Pressure (P) = 20 N/m 2. Initial volume (V 1) = 10 liter = 10 dm 3 = 10 x 10-3 m 3. Final volume (V 2) = 40 liter = 40 dm 3 = 40 x 10-3 m 3. Process 2 : Process (P) = 15 N/m 2
