A Fixed Amount of Ideal Gas Goes Through a Process

question 47

Essay

A fixed amount of ideal gas goes through a process abc.In state a,the temperature of the gas is 152°C,its pressure is 1.25 atm,and it occupies a volume of 0.250 m³.It then undergoes an isothermal expansion to state b that doubles its volume,followed by an isobaric compression back to its original volume at state c.(Hint: First show this process on a pV diagram.)The ideal gas constant is ,and 1.00 atm = 1.01 × 10⁵ Pa.
(a)How many moles does this gas contain?
(b)What is the change in the internal energy of the gas between states a and b?
(c)What is the net work done on (or by)this gas during the entire process?
(d)What is the temperature of the gas in state c?
