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.

Edición P3. A piston-cylinder system contains 1 L of water at 105°C and 85% quality. I know adds energy, causing the plunger to travel until it makes contact with a spring of constant K = 100 N/mm, just at this moment, the volume of the water is 50% greater than the initial. The energy transfer continues until the volume is 1.7 L, and the temperature of the water reached 600°C. Make a schematic of the system according to the statement and calculate the water pressure when T = 600°C. Answer: 198.16kPa
An ideal gas is compressed from a volume of V, = 6.00 L to a volume of V, = 3.00 L while in thermal contact with a heat reservoir at T = 295 K as in the figure below.

(a) Find the work done on the gas. kJ (b) Find the change in internal energy of the gas. k) (c) Find the thermal energy exchanged between the gas and the reservoir. kJ (d) If the gas is thermally insulated so no thermal energy could be exchanged, what would happen to the temperature of the gas during the compression? O The temperature would decrease. O The temperature would remain constant. O The temperature would increase.
