Concept explainers

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

### Problem Description:

A rigid tank is divided into two equal parts by a partition. One part of the tank contains 1.5 kg of compressed liquid water at 400 kPa and 60°C, while the other part is evacuated. The partition is now removed, and the water expands to fill the entire tank. Determine the entropy change of water during this process if the final pressure in the tank is 40 kPa. Use steam tables.

### Diagram Explanation:

- **The Tank:**
- The left section contains compressed liquid water.
- Initial conditions: 400 kPa and 60°C.
- 1.5 kg of water is present.
- **Vacuum:**
- The right section is initially empty.

Once the partition is removed, the water expands to fill the entire tank and the final pressure is 40 kPa.

### Task:

Calculate the entropy change of water during this process, using steam tables.

### Result:

The entropy change of water during this process is ____ kJ/K.

(Please fill in the result using appropriate calculations and steam tables.)
