Question: In a constant pressure process, the work done by the system is given by which equation?

Options:

Correct Answer: W = PΔV

Solution:

The work done by the system at constant pressure is given by W = PΔV, where P is pressure and ΔV is the change in volume.

In a constant pressure process, the work done by the system is given by which equation?

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.

Constant Pressure Process – A thermodynamic process where the pressure remains constant while the volume changes.
Work Done by the System – The energy transferred by the system during expansion or compression, calculated as W = PΔV.
Change in Volume (ΔV) – The difference in volume before and after the process, which is crucial for calculating work.
