Question:

Use V / V' = P' / P or D / D' = P / P' to find each quantity. (All pressures are absolute unless otherwise stated,
1. V' = 315 cm3, P = 101 kPa, P' = 85.0 kPa; find V.
2. V = 450 L, V' = 700 L, P = 750 kPa; find P'
3. V = 76.0 m3, V' = 139 m3 P' = 41.0 kPa; find P.
4. V = 439 in3, P' = 38.7 psi, P =47.1 psi; find V'.
5. D = 1.80 kg/m3, P = 108 kPa, P' = 125 kPa; find D'.
6. D = 1.65 kg/m3, P = 87.0 kPa, D' = 1.85 kg/m3; find P'.
