Based on the provided P-V diagram and data, calculate the relevant thermodynamic properties of the gas.

Here are the solutions to the questions based on the provided P-V diagram and information:

Given Data:

• Mass of gas, $m = 1 \text{ kg}$
• Adiabatic index, $\gamma = 1.4$
• Specific entropy at point 1, $s_1 = 0.515 \text{ kJ/kg.K}$

From P-V Diagram:

• Point 1: $P_1 = 100 \text{ kPa}$, $V_1 = 0.082 \text{ m}^3$
• Point 2: $P_2 = 6200 \text{ kPa}$, $V_2 = 0.
