P1 = initial gas pressure (N/m² or Pa)
V1 = initial gas volume (m³)
P2 = final gas pressure
V2 = the final volume of gas
T1 = initial gas temperature (K)
T2 = final gas temperature
P₁=10 atm
V₁=2.36 L
T₁=25+273=298 K
P₂=5.56 atm
V₂=7.79 L
![\tt T_2=(P_2.V_2.T_1)/(P_1.V_1)\\\\T_2=(5.56.* 7.79* 298)/(10* 2.36)\\\\T_2=546.91~K=273.91^oC](https://img.qammunity.org/2021/formulas/chemistry/college/ng0qklpzrisr854fcz28d4oq3a3wux1p96.png)
