A system is initially in an equilibrium state. It undergoes a process where the pressure decreases. What is true about the initial pressure, Pi , and the final pressure, Pf PfPi Pf=Pi Not enough information to determine A metal gas cylinder has a volume of 11.4L and contains 6.7 moles of chlorine gas (Cl2). It is stored at 20 degrees Celsius. What is the pressure in the cylinder (in atm)? Given: R=0.08206Latmmol1K1 and the molecular weight of Cl2 is 70.906g/mol Please give your answer to one decimal place. For example, if your answer is 12.625, please input 12.6 A closed sample of 1.6 moles of a monatomic ideal gas is in initially in equilibrium at T1= 731K and Vi=33.1L. The temperature is changed to Tf=538K, while the volume is held constant. What is P for this process? Give your answer in atmospheres (atm) to 2 decimal places, but do NOT include units. If your answer is negative, use the hyphen - (not the underscore) and do not add any spaces. For example, if your answer is 10.739atm, enter 10.74
