(a) A piston at 5.5 atm contains a gas that occupies a volume of 3.5 L. What pressure would have to be placed on the piston to force the volume to adjust to 0.73 L? atm (b) A piston at 46.0°C contains a gas that occupies a volume of 2.5 L. To what temperature would the gas have to be heated to increase the volume to 5.4 L at constant pressure? °C (c) A piston at 2795 torr contains a gas that occupies a volume of 4.7 L. What pressure would have to be placed on the piston to force the volume to adjust to 0.96 L?
(a)
Initial pressure, P1 = 5.5 atm
Initial volume, V1 = 3.5 L
Let us say that the final pressure = P2
Final volume, V2 = 0.73 L
Now, from Boyle's law (assuming at constant T)
P1V1 = P2V2
or, 5.5 x 3.5 = 0.73 x P2
or, P2 = 26.4 atm
Therefore, the pressure that has to be placed on top of piston = 26.4 atm

(b)
Initial temperature, T1 = 46.0 oC = (46 + 273.15) = 319.15 K
Initial volume, V1 = 2.5 L
Final volume, V2 = 5.4 L
Let us say that the final temperature = T2
From Charles' law,
V1/T1 = V2/T2
or, 2.5/319.15 = 5.4/T2
or, T2 = (5.4 x 319.15)/2.5
= 689.36 K
= (689.36 - 273.15)
= 416.21 oC
Therefore, the gas have to be heated to 416.21 oC.

(c)
Initial pressure, P1 = 2795 torr
Initial volume, V1 = 4.7 L
Let us say that the final pressure = P2
Final volume, V2 = 0.96 L
Now, from Boyle's law (assuming at constant T)
P1V1 = P2V2
or, 2795 x 4.7 = 0.96 x P2
or, P2 = (2795 x 4.7)/0.96
or, P2 = 13684 torr
Therefore, the pressure that has to be placed on top of piston = 13684 torr
