Questions & Step-by-Step Solutions

In a constant pressure process, the work done by the system is given by which equation?
  • Step 1: Understand that we are looking for the work done by a system when the pressure is constant.
  • Step 2: Recall that work (W) in a thermodynamic process can be related to pressure and volume change.
  • Step 3: Identify the formula for work done at constant pressure, which is W = PΔV.
  • Step 4: In this formula, P represents the constant pressure, and ΔV represents the change in volume (final volume - initial volume).
  • Step 5: Remember that if the volume increases, the work done by the system is positive, and if the volume decreases, the work done is negative.
