Show that the work done by an ideal gas during an isothermal change of state (from initial state 1 to final state 2), in a closed container is given by; 1W2=m.R.T(ln(v2/v1))
A piston-cylinder device contains 0.2 kg of air, initially at 27oC and 100 kPa. The air is then slowly compressed in an isothermal process to a final pressure of 400 kPa. Determine: (a) The work done during this process, and (b) The heat transferred.
