Linked Answer Q.25 & Q.26: A piston-cylinder arrangement contains an ideal gas mixture of $1\text{ kg}$ Nitrogen ($M = 28\text{ kg/kmol}$, $\gamma = 1.4$) and $2\text{ kg}$ of Argon ($M = 40\text{ kg/kmol}$, $\gamma = 1.667$), at $100\text{ kPa}$, $300\text{ K}$. The gas expands at constant pressure until the volume increases by $1\text{ m}^3$. The heat added is approximately
- A. 145.81 kJ
- B. 97.21 kJ
- C. 291.65 kJ
- D. 218.72 kJ
