A 220.0-mL sample ofhelium gas is in a cylinder with a movable piston at 105 kPa and 275 K. The piston is pushed m until the sample has a volume of 95.0 mL. The new temperature of the gas is 310. K. What is the new pressure of the sample?
According to the law, (P1×V1)/T1= (P2×V2)/T2 where P1=105 kPa, V1 = 220 mL amd T1=275 K, V2= 95 ml, T2=310K and P2=? P2= (P1×V1×T2)/(T1×V2) = (105×220×310)/(275×95) = 274.105 kPa
