Oxygen gas is commonly sold in 40.5L steel containers at a pressure of 141 atm. What volume (in liters) would the gas occupy at a pressure of 1.05 atm if its temperature remained unchanged? What volume (in liters) would the gas occupy if its temperature was raised from 21.0C to 37.0C at constant 141atm ? any help be wonderful
