17. I A 60.00 L fuel tank is filled with gasoline on a-10"C day, then rolled into a storage shed where the temperature is 20"C. If the tank is not vented, what minimum volume needs to be left empty at filling time so that the tank doesn't rupture as it warms?31. I A 24-cm-diameter vertical cylinder is scaled at the top by a frictionless 20 kg piston. The piston is 84 cm above the bottom when the gas temperature is 303"C. The air above the piston is at 1.00 atm pressure. a. What is the gas pressure inside the cylinder? b. What will the height of the piston be if the temperature is lowered to 15"C?4. The cylinder in FIGURE Q18.4 is divided into two compartments by a frictionless piston that can slide back and forth. If the piston is in equilibrium, is the pressure on the left side greater than, less than, or equal to the pressure on the right? Explain. Piston arc 20-C FIGURE Q18.46. A gas is in a sealed container. The gas pressure is tripled and the temperature is doubled. a. Does the number of moles of gas in the container increase, decrease, or stay the same? b. By what factor does the number density of the gas increase?65. I A container of gas at 2.0 atm pressure and 127-C is com- pressed at constant temperature until the volume is halved. It is then further compressed at constant pressure until the volume is halved again. a. What are the final pressure and temperature of the gas? b. Show this process on a pv diagram
