An insulated, rigid tank whose volume is 0.5 m³ is connected by a valve to a large vessel holding steam at 40 bar, 480°C. The tank is initially evacuated. The valve is opened only as long as required to fill the tank with steam to a pressure of 20 bar. Determine: (a) the final temperature of the steam in the tank, in °C, the final mass of the steam in the tank, in kg, and (b) the amount of entropy produced, in kJ/K.

![### Thermodynamics Problem
**Problem Description:**
An insulated, rigid tank whose volume is 0.5 m³ is connected by a valve to a large vessel holding steam at 40 bar, 480°C. The tank is initially evacuated. The valve is opened only as long as required to fill the tank with steam to a pressure of 20 bar.
#### Determine:
(a) The final temperature of the steam in the tank, in °C, the final mass of the steam in the tank, in kg.
(b) The amount of entropy produced, in kJ/K.
---
### Part A
**Your answer is correct.**
Determine the final temperature of the steam in the tank, in °C, and the final mass of the steam in the tank, in kg.
- \( T_2 \) = 660.25 °C
- \( m_2 \) = 2.338 kg
---
### Part B
**Your answer is incorrect.**
Determine the amount of entropy produced, in kJ/K.
\[ \sigma_{\Delta V} = 1.687 \text{ kJ/K} \]
