The air in a cylinder with a piston has a volume of 215 mL and a pressure of 625 mmHg. To obtain a higher pressure inside the cylinder at constant temperature, should the cylinder change as shown in A or B? Explain your choice in part (A). If the pressure inside the cylinder increases to 1.3 atm, what is the final volume of the cylinder? (The temperatue remains constant) Express your answer using two significant figures.

1. A rigid-sided flask contains an ideal gas at temperature 460o C and pressure 4.32 atm. If the flask is now heated to 801 oC, find the new pressure inside the flask, in atm. 2. In a certain heat engine: a fuel-air mixture is injected into a cylinder of volume 6.06 cc at pressure 7.08 atm and temperature 383o C. Now a piston comes down, compressing the gas to a volume 3.03 cc and pressure 64.2 atm. Find the Celsius...
