Thermodynamics Question 358
Question: One mole of an ideal gas expands at a constant temperature of 300 K from an initial volume of 10 litres to a final volume of 20 litres. The work done in expanding the gas is (R = 8.31 J/mole-K)
Options:
A) 750 joules
B) 1728 joules

Answer:
Correct Answer: B
Solution:
[b] $ W _{iso}=\mu RT{\log _{e}}\frac{V _{2}}{V _{1}}=1\times 8.31\times 300{\log _{e}}\frac{20}{10}=1728J $
