Calculate the constant external pressure required to compressed 1mole of an ideal gas feom volume 20litre to 8litre.when the work obtained is 44.9litre atm?

Dear student,

For any process the Work done on the system is given as
Work done = -V1V2PexternaldV
According to question, Putting the respective values,

Work done = -Pexternal208dv44.9 = -Pexternal ×(8-20)Pexternal = 3.74atm

Hope this helps,

Regards
