The volume of a given weight of gas varies directly as its absolute temperature t and inversely as its pressure p. If the volume is 4.45 m^3 when p=225 kilo pascals (kpa) and t = 305 K, find the volumn when p = 325 kpa and t = 354 k.

Answer 1

use the relation
P1*V1/T1 = P2*V2/T2
and solve for V2. They tell you all the other numbers. You can use the units provided.
225*4.45/305 = 325*V2/354
