Two moles of helium gas expanded isothermally and irreversibly at $27^{o} C$ from volume $1 d m^{3}$ to $1 m^{3}$ at constant pressure of $100 k Pa .$ Calculate the work done.

Options:

Answer:

Solution:

$W = - P∆ V$

Given, $P = 100 k Pa = 1 0^{5} Pa$

$V_{1} = 1 d m^{3} = 10^{- 3} m^{3}, V_{2} = 1 m^{3}$

$W = - 10^{5} \times (1 - 10^{- 3}) J$

$∴ W = - 99900 J$
