When the egg is hard boiled, there is

Options

A. Increase in disorder
B. Decrease in disorder
C. No change in disorder
D. `triangleG` is negati ve

Answer

### Step-by-Step Solution:

1. **Understanding the State of the Egg**:
- In an unboiled egg, the proteins (specifically albumin) are in a coiled or clustered form. This arrangement has a specific level of order.

2. **Effect of Heat on the Egg**:
- When heat is applied to the egg, it causes the proteins to denature, meaning they uncoil and lose their structured form. This transition from a coiled to an uncoiled state is crucial for understanding the change in disorder.

3. **Entropy and Disorder**:
- Entropy is a measure of disorder or randomness in a system. A coiled protein structure has less randomness (lower entropy) compared to an uncoiled structure, which is more random (higher entropy).

4. **Comparing States**:
- In the unboiled egg, the entropy is lower due to the ordered, coiled state of the proteins. In contrast, when the egg is hard-boiled, the proteins are uncoiled, leading to an increase in randomness and thus an increase in entropy.

5. **Conclusion**:
- Therefore, when the egg is hard-boiled, there is an **increase in disorder** (or increase in entropy). The correct answer is that the disorder increases.

6. **Spontaneity of the Process**:
- To determine if the process is spontaneous, we consider the Gibbs free energy (ΔG). A negative ΔG indicates a spontaneous process. However, boiling an egg requires the input of heat, which means it is not a spontaneous process. Thus, ΔG is not negative.

### Final Answer:
- When the egg is hard boiled, there is an **increase in disorder** (entropy increases).
