50 moles of neon is enclosed in a cylinder with a movable piston. By placing the cylinder in contact with various reservoirs and also insulating it at the proper times, the helium performs the cycle shown in the figure below. Process AB is adiabatic, BC is isothermal, CD is isobaric and DA is isochoric. Assume neon to be an ideal gas with Cp = (5/2)R and Cv = (3/2)R. Calculate Q, W, DU and DH for each step and the total Q, W, DH and DU for the whole cycle. A 80 В P [kPa] 30-- D 2.0 V [10-3m³] 4.0 Also, complete the following table: P (KPa) v (m3) T (K) Type of process (isothermal/adiabatic/etc) AU AH JA A->B B B->C C C->D D->A

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.
