Multiple choice

A gas expands in a frictionless piston–cylinder arrangement. The expansion process is very slow, and is resisted by an ambient pressure of 100 kPa. During the expansion process, the pressure of the system (gas) remains constant at kPa. The change in volume of the gas is 0.01 m3. The maximum amount of work that could be utilized from the above process is

  1. 0 kJ

  2. 1 kJ

  3. 2 kJ

  4. 3 kJ

C Correct answer
Explanation

$Given : p_a=100kPa, p_s=3000kPa,\triangle v=0.01m^3 \\ \text{Net pressure work on the system,}\\ \hspace{4cm}p=p_s-p_a=300-100=200kPa $
