**Title: Estimating the Temperature of Superheated Steam after Adiabatic Expansion**

**Description:**

The text describes a process involving steam and its expansion:

1. **Initial Conditions:**
   - A wet steam at 100.0 bar with a quality factor of 0.990 leaks through a defective steam trap.
   - The steam expands to a pressure of 1 atm.

2. **Process Stages:**
   - **Stage 1:** The expansion is rapid and adiabatic, leading to complete evaporation of the liquid droplets in the wet steam.
   - **Stage 2:** The steam cools at 1 atm to ambient temperature. In this stage, any change in kinetic energy (\(\Delta E_k\)) can be neglected.

**Objective:**

To estimate the temperature of the superheated steam immediately following the rapid adiabatic expansion.

**Educational Application:**

This scenario can be used to teach students about:
- Thermodynamic processes involving steam.
- Adiabatic processes and quality factor in steam.
- Application of thermodynamics in real-world scenarios like steam traps in industrial settings.
