two moles of an ideal gas are allowed to expand from a volume of 10 $d m^{3}$ to 2 $m^{3}$ at 300 K against a pressure of 101.325 kPa. Calculate the work done

Options:

Answer:

Solution:

$V_{1} = 10$ $d m^{3} = 1 0^{- 2} m^{3}, V_{2} = 2 m^{3}$
$P = 101.325 \times 1 0^{3} P a$
$w = - P Δ V$
$w = - 101.325 \times 1 0^{3} (1.99) = - 201.6$ $k J$
