  • question_answer
    The work done in expansion of an ideal gas from an initial volume\[{{V}_{1}}\]to a final\[{{V}_{2}}\]litres against a pressure of 1 atm at 300 K is

    A)  \[2.303R\times 300\,log({{V}_{2}}/{{V}_{1}})\]

    B)  \[2.303R\times 300\,log({{V}_{1}}/{{V}_{2}})\]

    C)  \[1\text{ }atm\times ({{V}_{2}}/{{V}_{1}})\text{ }litre\]

    D)  zero

    Correct Answer: A

    Solution :

    : \[W=nRT\,in\,\frac{{{V}_{2}}}{{{V}_{1}}}\] \[{{V}_{1}}=\]initial volume, \[{{V}_{2}}=\]final volume T = temperature, R = gas constant.
