P1=600  torrV1=10.0  LT1=27  C=27+273=300  KV2=8.0  LT2=300  KT1=T2=constantP1V1=P2V2P2=P1V1V2=600×10.08.0=750  torr=100  kPaP_1 = 600 \;torr \\ V_1 = 10.0 \;L \\ T_1 = 27 \;C = 27 + 273 = 300 \;K \\ V_2 = 8.0 \;L \\ T_2 = 300 \;K \\ T_1 = T_2 = constant \\ P_1V_1 = P_2V_2 \\ P_2 = \frac{P_1V_1}{V_2} \\ = \frac{600 \times 10.0}{8.0}= 750 \;torr = 100 \;kPa

Answer: 100 kPa
