Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

A piston-cylinder arrangement contains water at 110°C, 87% quality with a volume of 1 L. What is the initial mass, in grams? The system is then heated, causing the 150-mm- diameter piston to rise and encounter a linear spring with k = 800 kN/m. Calculate the specific internal energy (kJ/kg) at this instant knowing that the measured volume is 1.7 L. The heating continues and compresses the spring in the process. When the piston encounters the stops, the pressure is 200 kPa. What is the temperature (in °C) and entropy (in kJ/kg-K) at this point? Heating then continues until the pressure reaches 300 kPa. What is the volume, in L, at this instant? Illustrate the complete process in separate P-v and T-v diagrams. Hint: Draw the FBD of the piston in each state. wwwwwww D=0.15m H₂O
