The law that can be applied here is Charle’s Law which states that for a
fixed mass of gas and at constant pressure, the volume is directly proportional
with the absolute temperature. It is represented by the equation of
V1/T1=V2/T2. Since there is no negative volume, we will change the temperature
into Kelvin, (-123+273=150K) and (70+273=300K). plugging in the values, V2 =
(300K)(120mL/150K) we get a volume of 240mL.
