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.

Question 21 A rigid tank whose volume is 0.5 m, initially containing ammonia at 20°C, 1.5 bar, is connected by a valve to a large supply line carrying ammonia at 12 bar, 200°C. The valve is opened only as long as required to fill the tank with additional ammonia, bringing the total mass of ammonia in the tank to 136.7 kg. Finally, the tank holds a two-phase liquid-vapor mixture at 20°C. Determine the heat transfer to the ammonia in the tank from the surroundings, in kJ, ignoring kinetic and potential energy effects.
