The volume of gas varies directly with temperature and inversely with pressure. Volume is 100 m^3 when temperature is 1508 degrees and pressure is 15 lb/cm^2. What is the volume when the temperature is 2508 degrees and the pressure is 20 lb/cm^2?

v = kt/p , where k is a constant
using the given data
100 = k(1508/15
k = 1500/1508
so when t=2508 and p = 20
v = (1500/1508)(2508/20) = appr 124.73 m^3
