Problem

An ideal gas is taken through an isothermal process at a temperature of

300\,\text{K}

. a. (i) State the sign convention adopted in thermodynamics for the work associated with a system during a change in volume. b. (ii) For the given gas, explain qualitatively whether the work will be positive, negative or zero when the gas is compressed from

6.0\,\text{L}

2.0\,\text{L}

300\,\text{K}

. c. (iii) Without carrying out any numerical calculation, compare the magnitude of the work done during the compression in part (ii) with that during a compression from

6.0\,\text{L}

4.0\,\text{L}

at the same temperature. Give a reason for your answer.
