10 mole of ideal gas expand isothermally and reversibly from a pressure of 10 atm to 1 atm at 300 K . What is the largest mass which can be lifted through a height of 100 m

(Take g = 10 m/s² , R = 8 J mol^-1K^-1 )

Options:

Answer:

Solution:

$W = - nRT ln \frac{P _{1}}{P _{2}} = - mgh$

$10 \times 8 \times 300 \times 2.303 lo g 10 = m \times 10 \times 100$

$m = 55.2 kg$
