Question

When 5 moles of He gas expand isothermally and reversibly at 300 K from 10 litre to 20 litre, the magnitude of the maximum work obtained is ____ J. [nearest integer] 

(Given: R = 8.3 J K^-1mol^-1 and log 2 = 0.3010)

Answer 1

Answer is 8630 J

n = 5 mol

n = 300 K 

V₁ = 10 L 

V₂ = 20 L
