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 cylinder and piston assembly contains water at 105°C and 85% quality, with a volume of 1 liter. The system heats up, causing the piston to rise and encounter a linear spring. At this point the volume is 1.5 L, the piston diameter is 150 mm and the spring constant is 100 N/mm. Heating continues, so the piston compresses the spring. What is the pressure in the spring when the temperature reaches 600°C? 25%.
