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.

v = kt/p
Find k:
4.45 = k * 305 / 225
k = 3.28
Now, find the new volume:
v = 3.28 * 354 / 325
v = 3.56
