A gas contained within a piston-cylinder assembly undergoes three processes in series: Process 1-2: Constant volume from p₁ = 1 bar, V₁ = 4 m² to state 2, where p₂ = 2 bar. Process 2-3: Compression to V₁ = 2 m³, during which the pressure-volume relationship is pV = constant. Process 3-4: Constant pressure to state 4, where V¹ = 1 m³. Sketch the processes in series p-V coordinates and evaluate the work for each process, in kJ. Hint: Draw all the processes neatly on P-V diagram. Denote the states 1-4. Do not forget to add arrows.

A closed thermodynamic system consists of a fixed amount of substance (i.e. mass) in which no substance can flow across the boundary, but energy can. For a closed themodynamic system we cannot add energy to the system, via substance (E ) (1.e. matter which contains energy is not allowed across the boundary) Across the Boundaries E° = No Q = = Yes W mass NO CLOSED = Yes SY STEM m = constant | energy YES Figure 1.1. If the substance inside the thermodynamic system shown in figure 1.1. (i.e. piston cylinder device) is air, is the system a Fixed closed system Moveable closed system A. В.
3. If the temperature of a certain amount of gas is held constant, the absolute pressure of gas varies inversely as its volume without change of state, and if for certain amount of gas, the absolute pressure is 20 psi (pound per square inch) when the volume is 40 liters, then find the volume when the absolute pressure reached 32 psi. 4.

When the toy monkey is first hung on the spring and the system reaches equilibrium, the spring has stretched a distance of x = 17.6 cm, as shown in the diagram. This toy is so adorable you pull the monkey down an additional d = 7.6 cm from equilibrium and release it from rest, and smile with delight as it bounces playfully up and down. 1. Calculate the speed of the monkey, ve, in meters per second, as it passes through equilibrium. 2. Derive an expression for the total mechanical energy of the system as the monkey reaches the top of the motion, Etop, in terms of m, x, d, k, the maximum height above the bottom of the motion, hmax, and the variables available in the palette. 3.
