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 rigid tank with a volume of 0.1 m 3 contains water at 1.6 MPa and 300 °C. The tank is heated but, in order to maintain the pressure of the tank constant, a valve allows steam to leave the tank at an average temperature and pressure of 400 °C and 1.6 MPa, respectively. Determine the amount of heat transferred by the time the water has reached a temperature of 500 °C.
Liquid water is subjected to some process between an initial state of P1 = 52 psi, T1 = 43°F and a final state of P2 = 100 psi, T2 = 55°F. Determine the change in specific entropy, As12 (Btu/lbm-°R). Your Answer:
A rigid tank of volume 10 m³ initially contains saturated water vapor at a temperature of 120 °C. Steam at a pressure 1.2 MPa and a temperature of 400 °C enters the tank through a valve in steam line that is connected to the tank until the final pressure in the tank is 800 kPa, at which time the temperature is 200 °C.
