Gases and the Kinetic Molecular Theory1. A steel tank used for fuel delivery is fitted with a safety valve that opens if the internal pressure exceeds 1.00 x 103torr. It is filled with methane at 23oC and 0.991 atmand placed in boiling water at exactly 100oC. Will the safety valve open?2. A scale model of a blimp rises when it is filled with helium to a volume of 55.0 dm3. When 1.10 mol of He is added to the blimp, the volume is 26.2 dm3. How many more grams of He must be added to make it rise? Assume constant Tand P3. A steel tank has a volume of 438 L and is filled with 0.885 kg of O2. Calculate the pressure of O2at 21oC.Principles of General Chemistry, 2nded. By M. SilberbergChemistry, 8th ed.by W. Whitten, R. Davis, R., M. L. Peck, and G. Stanley.Exercises.
