Question

How much work is done an ideal gas at 77 F in expanding from a volume of 0.02 m3 to
220 L against a constant pressure of 6 x105 Pa and what will be a final temperature ?
a) 120kJ;3005C b)1.2x105 J;5441F c)120000 J;3278 K d)all of the above e)none

Answer 1

Final volume = 220 L = 0.220 m3

Workdone is given by

For finding temperature, we use ideal gas equation

For initial volume, ideal gas equation was

------(i)

At final volume, ideal gas equation is

------(ii)

Dividing eq (i) from (ii)

Or in Celsius

In Fahrenheit ,

Hence the correct option is (d) All of the above.
