The discussion centers on the application of the Combined Gas Law to find the final volume (V2) given initial conditions: P1 = 13.6 psi, V1 = 1.1 L, T1 = 22°C, P2 = 14.4 psi, and T2 = 32°C. Participants highlight the necessity of converting temperature to Kelvin and clarifying whether the pressure is absolute (psia) or gauge (psig). The final calculated volume varies among users, with one participant arriving at 1.07 L by assuming psia for the initial pressure. The conversation emphasizes the importance of accurate unit interpretation in gas law problems.
PREREQUISITESChemistry students, physics enthusiasts, and anyone involved in gas law calculations will benefit from this discussion, particularly those preparing for exams or practical applications in laboratory settings.
I also got 1.07 now. Initially I used 293 instead of 305 for some reason.gmax137 said:I got (b) 1.07 liter by assuming the 13.6 psi initial condition is psia. Also note, the initial volume is 1.1 liters; I missed that the first time thru (thinking it was 1 liters).
