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.

If a piston-cylinder system has V = 0.8m^3 of saturated water vapor at P1 = 250 kPa, at which the piston is sitting on a number of stops. The heat is slowly transferred to steam until the piston begins to move off of the stops at a pressure of P2 = 300 kPa, the heat transfer to steam continues until the volume doubles. a) draw the control volume, with assumed direction of work and heat transfers b) draw P-v diagram c) find final temperature

In a fixed volume tank, there is initially 0.8 kg of superheated water vapor at a temperature of 300°C and a pressure of 1 MPa. The final temperature drops to 120°C by drawing heat from the container and it is observed that the water has partially condensed. According to this; a) Volume of the tank b) Final state dryness x=?c) The amount of heat withdrawn from the tank as absolute value?
Solve correctly please. Two closed vessels of constant volume are connected by a valve. Container A contains 0.2 m' water at 400 kPa pressure and 80% dryness. In the B container, there is 0.5 m² of water at 200 kPa pressure and 250 °C. The valve opens and the water in the two containers becomes the same after a while. Assuming that the system has finally reached thermal equilibrium with the environment at 25 °C. a) Final pressure, b) Calculate the heat transfer during the phase change.

need answers in BTU
Some unknown gas undergoes a polytropic process, pV^1.5 = constant, the initial pressure, p1, is 1 bar, and the initialvolume, V1, is 1 m3. We also know the final volume, V2, is 4 m3. Please determine 1) the final pressure of the gas, p2, inbar; and the total work done by the gas, W, in kJ; 2) judge the direction of energy flow for the work: into the system or outof the system.
