Question: In a constant pressure process, how is the work done calculated?

Options:

Correct Answer: W = PΔV

Solution:

The work done in a constant pressure process is calculated using W = PΔV, where P is pressure and ΔV is the change in volume.

In a constant pressure process, how is the work done calculated?

In a constant pressure process, how is the work done calculated?

Step 1: Identify that the process is happening at constant pressure.
Step 2: Determine the pressure (P) of the system. This is a constant value.
Step 3: Measure the initial volume (V1) and the final volume (V2) of the system.
Step 4: Calculate the change in volume (ΔV) by subtracting the initial volume from the final volume: ΔV = V2 - V1.
Step 5: Use the formula for work done: W = P * ΔV.
Step 6: Multiply the constant pressure (P) by the change in volume (ΔV) to find the work done (W).

Constant Pressure Process – A thermodynamic process where the pressure remains constant while the volume changes.
Work Calculation – The formula W = PΔV is used to calculate work done during a constant pressure process, where W is work, P is pressure, and ΔV is the change in volume.
