The work done in expansion of an ideal gas from an initial volume v1 to a final v2 litres against a pressure of 1atm at 300 K is
Options
(a) 2.303 R ˣ 300 log (v2/v1)
(b) 2.303 R ˣ 300 log (v1/v2)
(c) 1 atm ˣ (v2-v1) litre
(d) zero
Correct Answer:
2.303 R ˣ 300 log (v2/v1)
Explanation:
W = nRT ln V₂/V₁, V₁ = initial volume, V₂ = final volume, T = temperature, R = gas constant.
