Suatu sistem gas berada didalam ruang yang fleksibel. Pada awalnya gas berada pada kondisi P1 = 1,5 × 10 pangkat 5 N/m2, T1 = 27°C dan V1 = 12 L ketika gas menyerap kalor dari lingkungan secara isobarik, suhunya berubah menjadi 127°C. Volume gas sekarang adalah..

Answer:

16.00L

Step-by-step explanation:

First you calculate the number of moles in the system:


PV=nRT\\\\n=(PV)/(RT)\\\\n=((1.5*10^5N/m^2)(12L))/((0.082L.atm/mol.K)(300.15K))=73134.16\ mol

To find the new volume of the system you use the following formula for an isobaric procedure:


T_2-T_1=(P)/(nR)(V_2-V_1)\\\\V_2=(nR)/(P)(T_2-T_1)+V_1\\\\V_2=((73134.16\ mol)(0.082L.atm/mol.K))/(1.5*10^5N/m^2)(400.15-300.15)K+12L\\\\V_2=16.00L

hence, the new volume is 16.00L
