SUMMARY
The discussion focuses on calculating the final temperature (T2) and pressure (P2) in a thermodynamic system where 1440 kJ/kg of heat is added to a gas with a specific heat capacity of 0.72 kJ/kgK and a heat capacity ratio (gamma) of 1.4. Given the initial conditions of mass (0.00058 kg), initial volume (V1 = 0.000005 m³), initial temperature (T1 = 753 K), and initial pressure (P1 = 25.12 Bar), the equations p2 = p1 * (v1/v2)^1.4 and p1 * v1 / T1 = p2 * v2 / T2 are utilized. The process is identified as a constant volume process, allowing for the calculation of T2 using the relationship Q = ΔT = Cv * ΔT.
