5 moles of a monatomic ideal gas for which c v =1.5 R are initially at a pressure of 2x10 5 Pa and occupy a volume of 1.25 m 3 . This gas expands while its pressure increases. The final pressure is 8x10 5 Pa and the final volume is 5.00 m 3 . The pressure is always proportional to the volume during this process. a. What is the initial temperature? b. What is the final temperature? c. What is the work done by the gas during this expansion? d. What is Q for this process?
