Answer to Question #239094 in General Chemistry for KING

Question

A sample of nitrogen gas expands in volume from 1.6 L to 5.4 L at constant temperature. Calculate the work done in joules if the gas expands against a vacuum

Answer 1

(a)Since work is done aginst vaccume = 0

-------------------------------------------------------------

Work done , W = PΔV

Where P = Pressure

ΔV= Change in Volume = V' - V

= 5.4 L - 1.6 L

= 3.8 L

= 3.8 × 10^-3m^3 (Since 1L^3 = 10^-3 m^3)
