Answer:
Option A, 7 L
Explanation:
Ideal gas equation,
[tex]\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}[/tex]
P1 = 1.2 atm
V1 = 10 L
T1 = 27 °C = 27 + 273 = 300 K
P2 = 2 atm
T2 = 350 K
[tex]\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}[/tex]
[tex]\frac{1.2\times 10}{300} = \frac{2\times V_2}{350}[/tex]
[tex]V_2=\frac{1.2\times 10\times 350}{2\times 300} = 7\ L[/tex]
So, option A is correct
